another integral question...

dy/dx = (sec^2 (x))(tan^.5 (x)) dx

just to be clear,

integral of secant squared of x times root tangent of x dx

we're supposed to use substitution to solve it. I tried u = sec x, but the problem is i've got a root tangent, not just tangent. can someone please walk me through it?

i've also got a similar issue with dy/dx = 3(sin x)^-2 dx
