Just a Post

Many are struggling towards happiness, but they don't know the very reason why they are unhappy.


It is just like an Athiest who does not believe in the existence of God but implying that God really exists.


Same as being keen in observing the shortcomings of others but does not see oneself's limitations.


Like defying love because of the experiences that resulted to pain.


 Is that a natural phenomenon of a HUMAN PERSONALITY or just a psychology of being imperfect.


I really do not know .


Is being rude a coping mechanism of not accepting the reality?


This is a mind over matter that we must dealt with.

THE OVERPASS: No Permit, No Exam





                Withstand sun’s penetrating rays, combat push and pull attacks of the people falling in line, skip meals, and witness the accent of tongue-lashing words.
                It was last August 2 when students huskily rushed to the luminous windows of The Finance Office like everyone’s in a race. They were waiting impatiently to be entertained. Some wee reprimanding for the priorities given to the parents while they tried their best to extend their palms to be given a priority number ranging from 1-1000. Their poses jumbled with huge drops of sweat constantly falling.
                Obviously  not all can pay exactly on a given due date, and hence should write a letter addressed to the Vice President of Finance in block form, no erasures if possible and reasonably stated. Of course, who among the college students have not written a promissory letter, ever since?
                I myself had experienced the tiring process of paying fees in partial. I had to get my assessment first, prepare my ID., observe keenly if somebody inserts in cuts through of the line, and if someone does how I am going to confront that person to fall in line properly. Worn out, the feeling of WOW would then be felt after receiving the four-sided sheets—the permit.
                Unfortunately   among thousands of students, many can’t still afford to pay their tuition or even half of it on time because of financial difficulties and so they will not be allowed to take the scheduled examination considering the NO PERMIT, NO EXAM policy. However according to the student handbook, these students, upon grant of their request take a special exam, provides that the garnered score is computed to 80% as the highest grade.
                Distinction among teachers is also taken account herewith. Few teachers disregard the presenting of permit in giving exams while others heed to the policy. Mr. Albert Musico said during the First General Assembly this school year that scores for special exams can still reach 100% provided valid reasons are given by a student, but what valid is varies by this matter. Hence, what is valid to one cannot be valid to another.
                September 10, 2009, Raymund Palatino of Kabataan Party list filed the House Bill 4791-Anti No Permit, No Exam in the Congress. This states that even in the absence of permit during Midterm and Final Exam in post- secondary level, examination must be given to the students, and a fine of Php 20-50,000 multiplied to the number of students will be charged to the teacher who violates it.
                Public’s reaction approved to it for sympathy and consideration. Palatino said that students with fees in arrears are usually disallowed from taking exam which may cause them to fail the subject and even experience humiliation.
                This column has nothing against the administration or the government. This is written not against an individual but an attitude. An attitude that causes students to experience downfall, gives students discouragement, and draws them to humiliation and shame.
                This is not a protest but a campaign. A campaign for the teachers to be more affectionate, helpful, and understanding to students with or without an examination permit, even before the existence of “ANTI-No Permit, No Exam.”
                I write this for the many unprivileged students. Educators want to mold productive students and by molding them, they give much attention to figures. Figures represented by grades, which are much affected by the 20 percent deduction due to special exams.
                Commission on Higher Education (CHED) already approved the aforementioned Bill but it still awaits certain deliberation and other legal process. Although I think the School Administration will not embrace abruptly to this, we are only asking understanding for the student’s sake. For the people in the Congress, I acknowledge your approval to the said Bill. I only hope that this will be totally implemented and recognized.

TEACHER( a subjective criticism)

What would a teacher really do in a class in which most of the students doesn't know how to deal with the SUBJECT MATTER? 




It is not really easy to become a teacher because you are going to teach students the best way that you can for them to become good citizens in the future.
But what happens when the teacher you want to have is different from what you have expected?


This is a fact. I do not write this because I hate teachers.I write this because I want the future teachers to be not like them.


Imagine that you are the only alien in a class and you don't know anyone there?Yes, you have a teacher
 but a teacher who is not existing.  A teacher that appears only  thrice or twice a week, gives quizzes which are not discussed,scolds us without doing anything wrong, and gives grades which does not respond to our performances.


We are paying for them to teach us but it appears that we are going to learn by ourselves. Where are the builders of tomorrow and the changers of lives? We don't want to be ignorant in any subject we enrolled ourselves.What are you going to do when you asked your professor about something then what you receive are insults and discrimination in return? Isn't that absurd especially if your teacher is a Doctor of Education? 


This issue is really a big deal for me for I'm studying to become a LEARNED PERSON! If this kind of teacher strikes my way, I will never step back for I am really a threat.

Basic Trigonometry

Introduction to Angles

Trigonometry is the study of angles and relationships between them. Especially important in trigonometry are the angles of a triangle. For this reason, trigonometry is closely linked with geometry. One of the major differences between trigonometry and geometry, though, is that trigonometry concerns itself with actual measurements of angles and sides of a triangle, whereas geometry focuses on establishing relationships between unmeasured angles and sides. To begin our study of trigonometry, we'll review the definition and some characteristics of angles to make sure we have a solid foundation for learning more about them.
Angles, by definition, lie in a plane, so trigonometry is a two-dimensional field of study. It will be convenient, and eventually necessary, to become familiar with the coordinate plane, which is a system of measuring and plotting points in two dimensions. The location of any point in a plane, then, can be specified by exact coordinates. A point can also be specified by a vector. A vector is like a line segment lying in a specific position--it has length and direction. Vectors can be used to determine the location of points, as well as the measure of certain angles. These basic concepts will provide a foundation for understanding the principles of trigonometry.
  
Angles Defined 

An angle is the union of two rays that share a common endpoint. The rays are called the sides of the angle, and the common endpoint is the vertex of the angle. The measure of an angle is the measure of the space between the rays. It is the direction of the rays relative to one another that determine the measure of an angle.
In trigonometry, angles are often defined in terms of rotation. Consider one ray, and then let it rotate a fixed distance about its endpoint. The ray in its initial position before the rotation, and the ray in its ending, or terminal position, after the rotation, creates an angle. The endpoint point about which the ray rotates is the vertex. The amount of rotation determines the measure of the angle. The ray in the initial position, before the rotation, is called the initial side of the angle. The ray in the terminal position, after the rotation, is called the terminal side of the angle. An angle created this way has a positive measure if the rotation was counterclockwise, and a negative measure if the rotation was clockwise.

Figure %: An angle defined as the rotation of a single ray
Note that a ray can rotate all the way around to its initial position, and possibly further, and still result in an angle with an initial and terminal side. This definition of an angle places no restriction on the magnitude of an angle (how far it can rotate). 




Measuring Angles

There are three units of measure for angles: revolutions, degrees, and radians. In trigonometry, radians are used most often, but it is important to be able to convert between any of the three units.

Revolutions

A revolution is the measure of an angle formed when the initial side rotates all the way around its vertex until it reaches its initial position. Thus, the terminal side is in the same exact position as the initial side. In trigonometry, angles can have a measure of many revolutions--there is no limit to the magnitude of a given angle. A revolution can be abbreviated "rev".

Degrees

A more common way to measure angles is in degrees. There are 360 degrees in one revolution. Degrees can be subdivided, too. One degree is equal to 60 minutes, and one minute is equal to 60 seconds. Therefore, an angle whose measure is one second has a measure of degrees. When perpendicularity is discussed, it is most often defined as a situation in which a 90 degree angle exists. Often degrees are used to describe certain triangles, like 30-60-90 and 45-45-90 triangles. As previously mentioned, however, in most cases that concern trigonometry, radians are the most useful and manageable unit of measure. Degrees are symbolized with a small superscript circle after the number (measure). 360 degrees is symbolized 360 o .

Radian

A radian is not a unit of measure that is arbitrarily defined, like a degree. Its definition is geometrical. One radian (1 rad) is the measure of the central angle (an angle whose vertex is the center of a circle) that intercepts an arc whose length is equal to the radius of the circle. The measure of such an angle is always the same, regardless of the radius of the circle. It is a naturally occurring unit of measure, just like Π is the natural ratio of the circumference of a circle and the diameter. If an angle of one radian intercepts an arc of length r , then a central angle of 2Π radians would intercept an arc of length 2Πr , which is the circumference of the circle. Such a central angle has a measure of one revolution. Therefore, 1 rev = 360 o = 2Π rad . Also, 1 rad = () o = rev.

Conversion between Revolutions, Degrees, and Radians

Below is a chart with angle measures of common angles in revolutions, degrees, and radians. Any angle can be converted from one set of units to another using the definition of the units, but it will save time to memorize a few simple conversions. It is particularly important to be able to convert between degrees and radians.

Figure %: The coordinate plane

The Coordinate Plane

Angles lie in a plane. To specify the point in space where an angle lies, or where any figure exists, a plane can be assigned coordinates. Since a plane is two-dimensional, only two coordinates are required to designate a specific location for every point in the plane. One coordinate determines the length, and the other determines width. In reality, length and width are the same thing--they are used because they describe distance in two directions which are perpendicular to each other. This is all the coordinate plane is: a plane with two perpendicular axes by which distance in either of two dimensions can be measured.
The coordinate plane consists of an origin and two axes. The origin is a point. The axes are lines perpendicular to each other that intersect at the origin. Below is pictured the coordinate plane, with the origin at point O.
The origin is fixed, and designated as the point (0,0). Every other point is assigned an ordered pair, (x, y) , according to its position relative to the origin. The two axes are named the $x$-axis and the y-axis. In most drawings, the x -axis is the horizontal axis, and the y-axis is the vertical axis, but this does not necessarily need to be the case. A point is assigned an ordered pair consisting of two real numbers: The first is the x-coordinate, which measures how far the point is from the y-axis. The second real number making up an ordered pair is the y-coordinate, which measures the distance between the point and the x-axis. Often the axes are pictured with tick marks indicating length to make it easier to measure distance. When a point is drawn into the coordinate plane and assigned an ordered pair, it is plotted. Take a gander at the plotted points below.

Figure %: Some points plotted in the coordinate plane
Note that some of the coordinates are negative numbers. Negative distance does not exist, but coordinates are given either positive or negative values to specify which side of the given axis they are on. In most cases, the positive direction of the x-axis points to the right, and the positive direction of the y-axis points upward. Thus, for example, points on the left of the y-axis have a negative x-coordinate. The positive directions don't always have to be these directions, though. Often, as in the diagram above, the axes will only have an arrow on the end which points in the positive direction. The other end has no arrow. This is how one can tell where the positive and negative values lie.
A plane extends in all direction without limit. So does the coordinate plane. Although there are many ways to draw the coordinate plane, it is always the same thing: a point of origin and two axes, which intersect at the origin and lie perpendicular to each other. The origin, by definition, always has the coordinates (0,0). Every other point in the plane can be measured according to the axes. Even the point (33563452143,23455434) exists and can be located in any coordinate plane; it extends without limit. Below are some other ways to draw the coordinate plane. All look different, but they are all the same coordinate plane.

Figure %: Different views of the coordinate plane
The axes of the coordinate plane divide the plane into four regions--these regions are called quadrants. The region in which the x-coordinate and the y-coordinate are both positive is called Quadrant I. Quadrant II is the region in which x < 0 and y > 0 . Quadrant III is the region in which x < 0 and y < 0 . Quadrant IV is the region in which x > 0 and y < 0 . The quadrants are labeled in the figure below.

The Beauty of IMPERFECTION


Imagine a perfect world with perfect people. 

Would forgiveness still exist?

Would people learn how to repent from their sins?

It's a matter of how our world is considered perfect for the existence of ANGER, WRATH and REVENGE

If nobody's hurt,
nobody will learn how to change and move on
nobody will stand up after a great downfall
nobody will aim for the betterment of all
nobody will strive harder

ALL IS WELL if the wellness is discerned well
not in a perfect manner in the absence of mistakes..
but in time when mistakes are modified and corrected
the way we want it to be..
