Integral of udu
NettetNow integrate: ∫ cos (u) du = sin (u) + C And finally put u=x2 back again: sin (x 2) + C So ∫cos (x2) 2x dx = sin (x2) + C That worked out really nicely! (Well, I knew it would.) But this method only works on some integrals of course, and it may need rearranging: Example: ∫ cos (x 2) 6x dx Oh no! It is 6x, not 2x like before. NettetTo perform the integration we used the substitution u = 1 + x2. In the general case it will be appropriate to try substituting u = g(x). Then du = du dx dx = g′(x)dx. Once the substitution was made the resulting integral became Z √ udu. In the general case it will become Z f(u)du. Provided that this final integral can be found the problem ...

NettetYou would need: ∫ 2x cos (x²) dx you have u=x² and du = 2x dx and that gives you: ∫ cos (u) du = sin (u) + C = sin (x²) + C. It turns out, though it looks simpler, ∫ cos (x²) dx cannot be integrated by any means taught in introductory integral calculus courses, but is a very advanced level problem.
