Homework Statement
compute the inverse derivative of f(x) = x^3/(x^2+1)
Homework Equations
n/a
The Attempt at a Solution
My issue is a purely algebraic one... getting the inverse function!
Attempting to solve for x yields no results!
y = x^3/(x^2+1)
y(x^2+1) = x^3
yx^2 + y = x^3
y = x^3 - yx^2
y = x^2(x - y)
y/(x-y) = x
cannot isolate x! help??
