"It's a trick," his granddaughter Mina said one winter evening, watching him erase for the tenth time.

"No," Elias whispered. "It's a door."

∫ x sin(x) dx → Integration by parts: let u = x, dv = sin x dx → du = dx, v = -cos x = -x cos x + ∫ cos x dx = -x cos x + sin x + C coroneos 100 integrals worked solutions

∫ e^x cos x dx → Integration by parts twice (or use complex exponentials): result = (e^x (sin x + cos x))/2 + C "It's a trick," his granddaughter Mina said one
