Math Help - New to Integrating, I need a lot of help

1. I'm really trying to. It's pretty complex for a beginner it seems (or so I think). I'll try and work some others out as the days come and post them on here for confirmation. Right now I understand about 30% of this. I'm trying though.

you're right. it is hard for a beginner. don't worry about it. it will come.

how about you pick a method you kinda like, and then go through it line by line, and ask questions to clarify your misunderstandings.

Evaluate to 4 significant digits: $\int_{-1} ^5\;\frac{5x^2}{\sqrt{x^3+3}}\;dx$
You know, this thread reminds me of that scene in Indiana Jones and the Raiders of the Lost Ark - the bit where some guy is twirling a sword around and Indy just shoots him.

If you're a beginner to integration and you've been asked for an approximate value of a complicated integral (complicated by beginner standards), just shoot it (this is a metaphor for use whatever technology you have at hand ......)

How much of a beginner are you?
