Hi, can you please help with question 2. Please keep any response easy to follow along with. Thank you!

Q).#2 Alternate Approach for Trig Integrals (not included on exams) Trig integrals also can be done using Reduction Formulas, for example : cos" x dx= - cos 1 (n-1) n -1 x sin x + [cos ("-2) x dx 17Final Answer a) evaluate this integral using the above reduction formula Final Answer b) evaluate this integral using the usual approach Final Answer c) show that results from (a) & (b) are equal. To do this, you may need to use cos x = 1 - sin x. Ignore, just see work at left
