Trigonometric Graphs Definition. Amplitude Period Phase Shift and Frequency. In other words instead of the graphs midline being the x-axis its going to be the line y -1.
Sine cosine tangent cotangent secant and cosecant. The inverse cosine function denoted by cos 1 x or arccosx is de ned to be the inverse of the restricted cosine function. 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.
As an example lets return to the scenario from the section opener.
The basic trigonometric functions are sine cosine tangent cotangent secant and cosecant. For example if we consider the graph of y sin x ysinx y sin x. In other words instead of the graphs midline being the x-axis its going to be the line y -1. The trigonometric functions include the following 6 functions.
