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.

- 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.

--Klosekam 15:26, 8 October 2008 (UTC)Shouldn't the answer to number 56 be pi/2 instead of pi/4 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.
