2. Hmm. I thought that, using Leibniz' Rule,

F'(x) = ln(8+3sinx)*cosx - ln(8+3cosx)(-sinx)

Did I miss something there?

That's the same as the integral of sin^2 x dx. Use integration by parts. Let sin x = u and sin x dx = dv v = -cos x du = cos x dx The integral is u v - integral of v du = -sinx cosx + integral of cos^2 dx which can be rewritten
