Saddle-point approximation

  1. Aug 19, 2008 #1
    Can the method of steepest descent (saddle point method) be used if an integral has the following form:

    [tex]\int exp\left[M f(x) + g(x)\right]dx[/tex]

    where M goes to infinity?

    I ask because all the examples I've seen of this method involve a function which is multiplied by a very large number, but never with only part of the function getting big.

    Nevermind, I figured it out.
