- You guys are life-savers.  I was doing them right, but on 50 and 56 I made stupid simple math errors like saying a half times two was a fourth...Thanks guys.

--[[User:Klosekam|Klosekam]] 15:26, 8 October 2008 (UTC)Shouldn't the answer to number 56 be <math> \frac{\pi}{2} - \ln{2} <\math> because you have to bring out a 2 before you take the integral meaning that you have to multiply the first part of the answer from above by 2.

I'm going to give my even answers so far just to compare and see if everyone else is getting the same. Some are a little weird in my opinion. I used a calculator on a few too. -By the way, go here and make sure your preferences are set right so it makes these easier to read.

$ 38: \pi $

$ 48: x - \arctan{x} + c $

$ 50: ln(9) - 4 $

$ 56: \frac{\pi}{4} - \ln{2} $

$ 84 a) : -\cos(\theta)+\frac{1}{3}\cos^3(\theta)+c $

$ 84b) : -\cos(\theta)+\frac{2}{3}\cos^3(\theta)-\frac{1}{5}\cos^5(\theta)+c $

I have corrected the answer to numbers 50 and 56.
