1. The problem statement, all variables and given/known data 1~~0 (x^7)/sqrt(4-3x^16) dx 3. The attempt at a solution There really isn't one. I am as clueless as one can get in calculus. I know that I am supposed to substitute the variable "u" in for a section of this problem, but really don't know anything after that. I understand derivatives but that is about it. If someone could walk me through this problem it'd be great.
