# Using numerical integration within solve or find_root

Hi there,

I have a function of two variable, u and Z: F(u,Z).

I would like to know for what value of u the integral of this function is zero. Could someone please help me with the syntax to do so?

I think I want to do something like: find_root(numerical_integral(F,Z,-infinity,infinity),0,1)

U must be between 0 and 1: 0<=u<=1 F cannot be solved symbolically.

Thanks so much!

A lambda expression might be useful here.
