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? Because the inverse of a function undoes the action of that ...

The inverse function theorem allows us to compute derivatives of inverse functions without using the limit definition of the derivative. We can use the inverse function theorem to develop differentiation formulas for the inverse trigonometric functions. ...

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 ...

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...
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...
Luke has taught high school algebra and geometry, college calculus, and has a master's degree in education. There's a lot to know about inverse functions, so let's review what we've learned. A function's inverse is another function that does the exact opposite, and we use the negative...
