Transformation Of Trigonometric Graphs Video Lessons Examples And Example 1. graph one full period of the function y = −2 sin 3x y = − 2 sin 3 x. the amplitude in this case is 2, 2, but since the coefficient is negative, this sine graph will begin by first going to the minimum value. the period of the graph will be 2π b, 2 π b, or in this case 2π 3 2 π 3 instead of 2π. 2 π. The basic sine and cosine functions have a period of 2\pi. the function \sin x is odd, so its graph is symmetric about the origin. the function \cos x is even, so its graph is symmetric about the y axis. the graph of a sinusoidal function has the same general shape as a sine or cosine function.

Graphs of the six trigonometric functions. note that sin, csc, tan and cot functions are odd functions; we learned about even and odd functions here. as an example, the sin graph is symmetrical about the origin $ (0,0)$, meaning that if $ (x,y)$ is a point on the function (graph), then so is $ ( x, y)$. it also means that for the sin graph, $ f. This cosecant function will have the form a c s c (b x c) d. since its period is 8 π and the period of the basic cosecant function is 2 π, it is possible to solve for b using the equation 2 π b = 8 π. in this case, b = 1 4. then recall that the midline is normally at the x axis, the line y = 0. 1 hr 23 min 10 examples. graphing trig functions review. example #1: graph the sine function over two periods. example #2: graph the secant function over two periods. example #3: graph the tangent function over two periods. example #4: graph the cotangent function over one period. example #5: graph the cosine function over one period.

This means the graph of the function has the same output at exactly the same place in every cycle. and this translates to all the cycles of the function having exactly the same length. so, if we know all the details of one full cycle of a true periodic function, then we know the state of the function’s outputs at all times, future and past.
