Homework Statement


The integral of 5*(sin(6x)/sin(3x))dx

The Attempt at a Solution



I'm not quite sure what to do with this one. I moved 5 to the left of the integral, but then I'm lost. Apparently I'm rusty on these trig identities.

Could anyone help me get started? Thank you.

Look up the double angle formula for sine, wikipedia is good. You should be able to simplify with the bottom some then.
