Right, or wrong? Say which for each formula and give a brief reason for each answer. a. - 2x sin x dx = - x sin x + C b. - 2x sin x dx = 2x cos x + C C. - 2x sin x dx = 2x cos x - 2 sin x + C a. Choose the correct answer below and fill in the answer box to complete your choice. d O A. The formula is wrong because dx ( -x2 sin x) = d O B. The formula is right because dx (-x2 sin x) =
