Hello, DarthPipsqueak!
I hope you're familiar with Trig Substitution.
I'll get you started on the second one . . .
Can you finish it now?
How do I integrate these problems?
integral[3/(x^2)(sqrt(25-x^2))]
aaaand if possible this one:
integral[(x^2)/sqrt(25-16x^2)
thank you so much! My book doesn't have any examples like this and I'm having trouble because I keep messing up somewhere in the problem.
