due to technical prob answer isnt displaying
answer is 2ln3 – 3ln2
simply put y = cosx and then use partial fractions for y/(y+1)(y+2)= A/(y+1) + B/(y+2)

You can go for this easy method: Put Cos^2x =t then upper numerator will be gone in dx itself. A quadratic eqn will be there in denominator which is easy to solve
