1. im soooo stuck on this homework. please can someone help me do it if you can >.< would be very grateful...

1) find, exact values of integral of xlnx and then there is e on the top and 1 on the bottom of the integral...

2) find exact values of integral of xsin0.5x, with 0.5pi on top and 0 on the bottom.
2. ∫ xlnx dx = (0.5x²)lnx - ∫ 0.5x²(1/x) dx = [(0.5x²)lnx - 0.25x²]

∫ xsin(0.5x) dx = -2xcos(0.5x) + ∫ 2cos(0.5x) dx = 2[-xcos(0.5x) + 2sin(0.5x)]

And sub in the limits...
3. ooo thank you so much lol but i still dont get the second one. was U = sin0.5x or x
4. u=x and dv/dx=sin(0.5x).
5. okies thank you very much
