GRAPHS OF RECIPROCAL TRIGONOMETRIC FUNCTIONS

A brand new day for brand new topic, lets look at some reciprocal trigonometric functions. First of all, we need to know what is the reciprocal for sine, cos and tangent. reciprocal of cos is sec, sin is csc, tangent is cot. Some people may confuse of csc and sec. I personally like to remember in the way that, sec ends with 'c' so is is reciprocal of cos while the middle of csc is 's' so it is reciprocal of sin. Well, the reciprocal graph is totally different from the normal graph. This link explain about the reciprocal trigonometric functions. http://mathworld.wolfram.com/InverseTrigonometricFunctions.html 

So we can find the angle from the graph, we can also find the y value when we are given the angle. Lets call it a day. T.N.T ADVANCE FUNCTION FREAK  XD

CHAPTER 5 TRIGONOMETRIC FUNCTIONS

 Hey everyone, now going into a new chapter, maybe not that new for Malaysian students as we took add math before which have a connection with what we will be studying. Lets start with graph of sine, cosine, and tangent.

Sine graph:

cos graph:

 tangent graph:

May refer to the link under the graph for more information. http://www.analyzemath.com/trigonometry/properties.html
but the story does not end here. The graph can also be transformed in the way polynomial functions can. The video shows how transformation works.

Ok, thats all for today!! have fun and try out the questions in text yea....
