Dear sean123,

Do you mean, $\displaystyle \int_{0}^{9}\left(1+y^{\frac{1}{2}}\right)^{\frac{ 1}{2}}dy$

Try the substitution $\displaystyle y = (s-1)^2$ and see how it goes...

yes, i think that's what sean123 means, i have the same problem that i can't solve

Dear confusedgirl,

Then maddas' substitution will surely solve the problem.
