Calculus (Derivatives of Inverse Functions)
Suppose f(x) = sin(pi cos(x)). On any interval where the inverse function y = f^-1(x) exists, the derivative of f^-1(x) with respect to x is: I've come as far as y = arccos ((arcsin(x))/pi), but I am not certain this is right.

Pre Calculus 12
Here is the way I do these: y = (2/3)x - 4 to find the inverse, I follow these steps 1. to find the inverse equation, simply interchange the x and y variables So the inverse of y = (2/3)x - 4 is x = (2/3)y - 4 2. Now you want to probably solve this for y so multiply each term ...

verify that the functions of f and g are inverse of each other by showing that f(g(x))=x and g(f(x))=x; f(x)=In(x-1),g(x)=1+e^x

verify that f and g are inverse functions. f(x) = 5x^2 x>(or equal too)0 g(x)= (x+2/5)^1/2

Your notation is confusing and your equation is ambiguous without parentheses. If F(x) = 6/(x+4) = y, the inverse function F^-1 (x) is the operation that, if applied to y, will give you x. x +4 = 6/y x = (6/y) -4 Finally, switch variables. F^-1(x) = (6/x) - 4 Note that if you ...
