NettetNow, solve the second integral, let us assume cos x = u. therefore, - sin x d x = d u. substitute the value, - ∫ sin x. cos 2 x d x = ∫ u 2 d u ⇒ - ∫ sin x. cos 2 x d x = u 3 3 + C ⇒ - ∫ sin x. cos 2 x d x = 1 3 cos 3 x + C. Combining all the above, ∫ sin 3 x d x = cos x + 1 3 cos 3 x + C. Hence the required value of ∫ sin 3 x d ... Nettet7. nov. 2024 · asked Nov 7, 2024 in Integrals calculus by Abhilasha01 ...
