For each question, state 'Correct' if the solution is valid and 'Incorrect if the solution is invalid. If the solution is invalid, you must explain why briefly. (Do not solve the problem: just point out an error if a solution is wrong). (a) S-12dx. dx = In|x|121 = In|1- In-1= 0 (b) sin ? 2x cos 2x dx Let u = sin 2x. Then, du = cos 2x dx. Is sin? 2x cos 2x dx = [ u? du = $u? + c = 3 sinº 2x + 4 2° u
