Nettet24. feb. 2024 · Much too much work, if you want ∫ sin 7 x cos 3 x d x. When either of the exponents is odd, there’s a supereasy way of handling the problem without using a reduction formula: write cos 3 x = ( 1 − sin 2 x) cos x, to get ∫ ( sin 7 x − sin 9 x) cos x d x, and make the substitution u = sin x, d u = cos x d x. Share Cite Follow Nettet24. okt. 2014 · I didn't distribute cos (x) and therefore my solution was different: x - 1/3 (sin^3 (x)) + C instead of sin (x) - 1/3 (sin^3 (x)) + C. I feel that when I do distribute my professor does not and ends up finding a different solution than what I would have done …
