# Math Help - More Integration

1. ## More Integration

Sxsn(2x) dx

2. Is this your integral: $\int x\sin (2x) dx$

As you suggested, do integration by parts: $\int u dv = uv - \int vdu$
$\begin{array}{lll} u = x & \quad & dv = \sin 2x dx\\ du = dx & \quad & v = \int (\sin 2x ) dx \end{array}$

3. Sorry about the type and thanks~
