Whats the integral of ln(cosx+1)? By the way don't give me the answer, give me the basic idea, i want to find the solution myself(i love integrals ). I tried to multiply by x'(=1) and then integrate by parts but the integral became even more complicated. I really need to calculate this one so i can calculate another integral. Also are there any general methods to calculate any ln(P(x))?
