Thanks so much, bossk171!

I guess the distributive property here was the key. I didn't think to take the 3 out like that and then multiply (1/3) by the integral, thanks so much!

Re: "u-substitution" integral problem

No problem, to be honest (which is something everyone should be) I saw this when you first posted it and decided that it was a little too hard for me, and I figured that someone smarter than me (JaineFairfax or Ricky or someone) would come along and take care of it.

When no one did, I jumped over to The Integrator and plugged it in. When I saw the answer I kinda just worked backwords.

I'm glad I took the time to answer this, it keeps my brain cells moving.
