HERE IS the definition of functions being inverses:Functions f(x and g(x) are inverses of one another, means: f(g(x)) = x and g(f(x)) = x, for all values of x in their respective domains.Why does it mean that?

In 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 angle, or 0. If x is ...
The algebra of inverse functions can be tricky, but the calculus of their derivatives is much easier – just look in the infinitesimal microscope. 21.2. The Derivative of the Inverse Hint 21.3. The Inverse Function Rule (1) Differentiate both sides of the general equation x = g[f[x]] and...
In fact, if we add up the heights of the function values in the two graphs above, we can get \pi/2 for any value of x. \sin ^{-1}(x)+\cos ^{-1}(x)=\frac{\pi}{2} \\ for any x in the interval [−1, 1]. This can be proved by calculus.(How?) But we can also...
