I am having trouble with my project in a change of variable integral and the problems that follow after it. In the photos contain three differential equations and the problem set that follows. I need help with items 5 through 9. The more detail the better. I am not understanding how this thing works. I almost got the substitution to work in in item 5 and I got the integrand in item 6. I am having difficulty invoking items 8 and 9 just because I don't understand what is going on there.
I was having trouble with the picture up-loader. Here are the links to the thing I have questions on.
