Sin x cosx cos'x+ 3 cos x +2 dx equals put cos x t, then tdt t dt p+3t+2t1(t+2) 2 dt t+2 t+1 =[2 log (t+2)-log(t+1)), = 2 log 3- log 2-2 log 2 + log1=log (9

sin x cosX cos'x+ 3 cos x +2 dx equals Put cos x t, then tdt t dt P+3t+2t1(t+2) 2 dt t+2 t+1 =[2 log (t+2)-log(t+1)), = 2 log 3- log 2-2 log 2 + log1=log (9 /8) please explain this problem
