Consider:

The inverse of the function requires using a special function called the Lambert W-function: .

What you want is even more complicated .....

Why do you want the inverse, anyway?*Note: If you have to find the derivative of the inverse function for a particular value of z, this can be done without using an explicit rule for the inverse ......* - Mar 10th 2008, 06:58 AMThePerfectHacker
Maybe this function does not even have an inverse? Does it?
