Anyone good with solving definite integrals?
This problem has been bugging me for a while now.
integrate: x*sin(x)*cos(2x) for x = pi to pi/2
I know I have to use Simpson's formulas and integration by parts, but I just can't seem to get the right solution: 5/9 - pi/3
Any help would be greatly appreciated.
