I have a non-negative analytic function f[x] whose area (integral of f[x] from 0 to Infinity) is unity. I want to find the upper limit such that the integral up to that limit will contain a fixed fraction of the total area, i.e. find a such that Integrate[f[x], {x,0,a}] == f (f<=1) The question is, what's the most efficient way to program this, if I want to find a with fair accuracy, and with a variety of different functions f[x]? Thanks . . .
