I finally got the first one. so just the 2nd and 3rd problems now.

thank you. I am going to try this right now. for the third i got down to an integral that would need partial fraction decomposition but got stuck. :(

I have three problems that I'm having a hard time with. I'd appreciate any help with any of the three problems. \int((cos(x))^6)dx AND \int(x^3 * sqrt(x^2 - 1) AND Solve for y (separation of variables): dy/dx = ((2y +...
