the point is that only the most trivial integrals can be solved analytically. approximations are extremely important, anyone working in an applied field pretty much has to give up on closed-form solutions. of course it's important to know the stuff you learn in calculus B, but i'm assuming your teacher just meant that there really aren't that many techniques for analytically solving integrals. you learn integration by parts, substitution, and a handful of other tricks and that's pretty much what you have to work with.
