Nettet5. feb. 2015 · So, ∫ f could be considered the set of functions which have a derivative f. There are many functions which have the derivative sin, and they are all of the form − cos + C, where C is some real number. This is why it is said the integral of sin is − cos. But why does the integral then not represent the area? Well, it does. NettetLet's look at the integral as follows: If u = sin x and d v = sin x d x, then d u = cos x d x and v = − cos x. So we have ∫ sin 2 x d x = u v − ∫ v d u = − sin x cos x + ∫ cos 2 x d x If we add ∫ sin 2 x d x to both sides, we get: ∫ sin 2 x d x + ∫ sin 2 x d x = − 1 2 sin 2 x + ∫ 1 d x = − 1 2 sin 2 x + x + C and so NettetRewrite the integrand: Integrate term-by-term: Use integration by parts: Let and let ..
