Check the work below when integrating f sin? (a) . cos (x) da . Indicate where the mistake is initiated (if any). Integrate: f sin? (x) . cos? (x) dx Step 1: = S 1-cos(2x) 1+cos(2x) da 2 2 Step 2: = - f (1 - cos(2x)) . (1 + cos(2x) ) da Step 3: = 1 S (1 - cos? (2x) ) dx Step 4: = 1 (x - sin? (2x)) + C Step 5: = = (x - 1sin(4x) ) + C
