Unlike inverse sine and inverse cosine, the inverse tangent function has horizontal asymptotes. the vertical asymptotes x= \pi/2 and x = −\pi/2 of the tangent function have become horizontal asymptotes of the inverse tan function. This means that we have the following useful limits: \lim ...
To define the inverse functions for sine and cosine, the domains of these functions are restricted. The restriction that is placed on the domain values of the cosine function is 0 ≤x≤ π (see Figure 2 ). This restricted function is called Cosine. Note the capital “C” in Cosine. Figu...

Inverse sine,cos, tan --What they are and how to use them to find the measure of an angle in a right triangle.
(Note: you can read more about Inverse Sine, Cosine and Tangent.)Careful!Did you see the "Careful!" column above? That is because some inverses work only with certain values.Example: Square and Square Root When we square a negative number, and then do the inverse, this happens: Square:...
