I would be extremely susprised if it has a closed form for the integral.

Thanks. I'm new and don't know a lot.. However the ti-84 will give me a value for a definite integral. I don't know how.

Exactly what definite integral are you entering? That is, what are the integration limits? Is the answer "symbolic" or "numerical"?

A specific definite integral can be way easier than an analytic expression for the indefinite integral.
