Generalize this to fine a formula for the integral:

sin(ax)cos(bx)dx

Could someone tell me what they got for an answer so I can check it to see if my answer is right.

My answer:

-1/2sinasinbx^2-1/3acosaxcosbx^3+ integral 1/3 a^2cosbx^3sinax..I'm not sure hot to find the integral of the last part.
