There are six trigonometric functions sin θ, cos θ, tan θ, cot θ, tan θ, cosec θ, and sec θ. The domain and range of trigonometric functions are given by the angle θ and the resultant value, respectively
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 ...

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 ...

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. Range and domain of arccosRecall that the domain of a function is the set of allowable inputs to ...
Graphs and Functions 4.2.2 Inverse of function f−1(x) Definition of inverse function f−1(x) Let f be a one-to-one function with domain D and range R. Then its inverse f−1 has domain R and range D, that is, f(x) = y ⇔ f−1(y) = x, for any y in R and x...
