cananyone please answer the two red boxes pleasee

We already know we can do the following problem using u-substitution, with u = sin(112) | sin (117) cos(112) de = We see that / sinº(112) cos'(112) dz is solved similarly, because A. the exponent of sin is odd. • B, the exponent of cos is odd. C. None of the above So we'll still use u-substitution with u = sin(11x), after first rewriting cos' (11x) = cos (112) cos(11x) and usin Select the trigonometric identity needed to solve this problem. u 2 A. 1 + cot? u = csc? B. sin?u= 1 - cos(2) C. cos?u= 1 + cos(2) 2 D. sin u + cos?u= 1 E. tan u + 1 = secu F. None of the above . Finally, put it all together to calculate sin (11x) cos' (11x) dr Hints will appear after 3, 6, 9, and 12 attempts.
