Date: 9/5/96 at 10:19:25 From: Doctor Jerry Subject: Re: Primitive function I assume that the term "primitive function" refers to the integral. I doubt that this particular integral is expressible as a finite combination of elementary functions. Moreover, Mathematica was unable to find an antiderivative. This is more evidence that the integral is not expressible as a finite combination of elementary functions. If this is true, it's not a tragedy; indeed, it is more likely that a randomly selected integral (whatever randomly selected means) is not integrable in the above sense than otherwise. -Doctor Jerry, The Math Forum Check out our web site! http://mathforum.org/dr.math/
