Is there any application for the derivative of the inverse function?

[awaizy]

In my math class we are learning about inverse functions and how you can find if the inverse of a function is a function using the first derivative test. Our teacher omitted some of our homework regarding the derivatives of the inverse and he posed the question of how one would practically use the derivative of the inverse function in a real-life situation.

I did some research on it, but beyond information about how to find it, I came up with nothing.

Any one know some uses?

Thanks in advance.

If anyone is interested, I found this one page online after a while of searching:
