Trigonometry Graphs Math

This post is going to help you pass algebra 2 trig.

Trigonometry graphs math. On the x axis are values of the angle in radians and on the y axis is f x the value of the function at each given angle. Hi everyone and welcome to mathsux. Plot of the tangent function. In this post we are going to apply our knowledge of the unit circle and trigonometric functions to graph y sin x y cos x and y tan x.

Sine cosine and tangent are the three important trigonometry ratios based on which functions are defined. Graphs of y a sin bx c and y a cos bx c helps you to understand the displacement or phase shift of a trigonometric curve. The tangent function has a completely different shape. In these trigonometry graphs x axis values of the angles are in radians and on the y axis its f x is taken the value of the function at each given angle.

At π 2 radians 90 and at π 2 90 3 π 2 270 etc the function is officially undefined because it could be positive infinity or negative infinity. It goes between negative and positive infinity crossing through 0 and at every π radians 180 as shown on this plot. Graphs of y a sin bx and y a cos bx introduces the period of a trigonometric graph. Below are the graphs of the three trigonometry functions sin x cos x and tan x.

Amplitude is a indication of how much energy a wave contains. Graphs of y a sin x and y a cos x talks about amplitude. If you have any questions don t hesitate to comment or check out the video below. Working with the graphs of trigonometric functions trigonometric graphs can be sketched when you know the amplitude period phase and maximum and minimum turning points.
