These look good. You can always find dy/dx of the answer to check them.
Awesome, thanks! I appreciate your help. I wish I could try more...I emailed my prof. and he said all of the ones in the book are too high a level and he hasn't taught it yet. Guess I'll just have to wait. Also, note that I added one more question.
I assume 4. is Make the substitution .
Yeah, that's it. I did make that substitution. What did I do wrong? I thought sin^5x and sinx^5 were the same thing? Or am I seriously mistakin'?
If you write we can't tell if it's or ... So after you make the substitution , what's ? What's ?

So what is your new integral in terms of u?

Looks good.
Sweet, thanks! Can't wait for the more challenging ones.
