Integration Tables

  1. Nov 4, 2006 #1
    Does anyone know of any online integration tables that are fairly robust?

    I need to know how to integrate [tex]\int x sin(ax) sin(bx) dx[/tex]

    integrals.wolfram.com/index.jsp doesn't work?

    EDIT: Lol.... I forgot how it bungles trig... it probably gives a right answer, but it's not the one you want

    The calculator gave me [tex]\frac{1}{2}(\frac{cos((a-b)x)}{(a-b)^2}-\frac{cos((a+b)x)}{(a+b)^2}+\frac{xsin((a-b)x)}{(a-b)}-\frac{xsin((a+b)x)}{(a+b)})[/tex]

    Is this correct?
