That's a great example! If you would add more information, I think the OP will have a much better understanding of what's happening. :D 2d comment Seemingly hard integrals which are made easy via differentiation under the integral sign a.k.a Feynman Integration @O.L. I thought it would be nice to have a list on math.se with explanations provided by experienced users to look at and furthermore, for people new to the technique to look it's power and see how it applies to a wide range of integrals. 2d asked Seemingly hard integrals which are made easy via differentiation under the integral sign a.k.a Feynman Integration 2d comment Evaluating $\int_{0}^{\infty} \frac{x^{3}- \sin^{3}(x)}{x^{5}} \ dx$ using contour integration Are you aware of any tutorials which explain this method in detail? For example, how it works and the motivation behind it? Thanks! 2d comment Evaluating $\int_{0}^{\infty} \frac{x^{3}- \sin^{3}(x)}{x^{5}} \ dx$ using contour integration What integration technique is this? Jul25 comment Evaluating $\int_{0}^{\infty} \frac{x^{3}- \sin^{3}(x)}{x^{5}} \ dx$ using contour integration How did the $\sin^3 x$ become $\frac{1}{4} \sin 3x - \frac{3}{4} \sin x$?
