The range of y = arcsec xIn calculus, sin−1x, tan−1x, and cos−1x are the most important inverse trigonometric functions. Nevertheless, here are the ranges that make the rest single-valued. If x is positive, then the value of the inverse function is always a first quadrant ...
Computing inverse trig functions How would you simiplify \sin ^{-1}\left(\sin \left(\frac{13 \pi}{10}\right)\right) ? \\ The knee-jerk reaction is to cancel out the inverse sine and the sine, leaving only 13\pi/10. This can’t be correct, though—the range of inverse sine ...

In this lesson, learn what inverse trigonometric functions are, including inverse sine and inverse cosine functions. See examples to learn how to...
By limiting the range to see all of they-values without repetition, we can define inversefunctionsof the trigonometric functions. It is possible to form inverse functions at many different locations along the graph. The functions shown here are what are referred to as the"principal" functions. ...

For more on this see Inverse trigonometric functions. To solve this problem, the range of inverse trig functions are limited in such a way that the inverse functions are one-to-one, that is, there is only one result for each input value. ...
