The inverse of a function y = f ( x ) is the function x = g ( y ) whose rule un-does what the rule for f does. It is sometimes easier to compute the derivative of the inverse function and invert for the derivative of the function itself. Also, the inverse function rule can be...
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 thus use the Chain Rule to explain symbolically that if y = f[x] and x = g[y] have the same graphs and if both derivatives f′[x] and...
Find the derivative of the inverse of function \( f \) given by \[ f(x)= \dfrac{x}{2} - 1 \] We presentto answer the above question. In the first method we calculate the inverse function and then its derivative. In the second method, we use the formula developed above. The fir...

This rule is applicable to any derivable function for which we can determine its inverse function [f−1]′(a)=1f′[f−1(a)]. Answer and Explanation: Using the rule of the derivative of the inverse function: {eq}{\left[ {{f^{ - 1}}} \right]^\pr...
INVERSE FUNCTION THEOREM where I is the identity map. We conclude that DF ?1(q0) = DF (p0) ?1, in other words, the matrix of the derivative of the inverse map is precisely the inverse matric of the derivative of the map. So when the inverse map is C1, DF (p0) must be ...
