Simple question in Mathematica: find value of function

  1. Aug 10, 2011 #1
    Hi guys!

    I'm trying to the value of x when a function F[x] has a certain expression. I'm computing the value of F[x] using NDSolve and a set of differential equations - all numerically. Yet, I cant find an easy and systematic way to find the value of x when F[x]=constant.

    I tried using NMinimize:
    Code (Text):
        F[x] /. systemofequations, x]
    Yet, I cant seem to find a good way to compute the value of x.. :S

    Do you guys have any suggestions on how I could try to solve this issue?
    Thanks so much
