Question 3, MATH 105, April 2010

Excellent! Then seems both agree, I'm writing it as QGH and QGS and will restore my version since it seems to be mostly the same with slightly more details. Feel free to edit it if you think it could be improved (for example I'm not sure if I should just keep fractional powers everywhere).

And this also means this exam is done now!

And if you could review my work there: Science:Math_Exam_Resources/Courses/MATH101/April_2010/Question_2_(a) we would finish off that exam as well!

Looks good!

I've added a second solution, using the washers method, which is a lot simpler for this question. Could you review it?
