*EDIT - Sorry, I was typing on a phone, and missed a couple of key bits of information on the equation. Have fixed them up :/
I just have a quick integral question in which I can not figure out how to get the right answer. Or, I know what I have to do to get it, I just don't know WHY I can do it...No answers please, just a tip in the right direction
Now, have I got this set up right? U-substitution still confuses me a little, and I'm not sure if I've done it properly. If I go ahead and finish this equation, I get.
I should be getting
I can see how I should be getting that answer - by inverting the 3/2, to make it 2/3. But why is the 3/2 being inverted to 2/3 in the first place? The only reason I can think of is that it's in the denominator of a fraction, so it would be inverted, but I'm not sure...
