Hey again,

Looks like integration by parts is real trouble for me

I have a problem that I must integrate:

$\displaystyle \int{s2^s}ds$

I set:

$\displaystyle u=s$

$\displaystyle dv=2^s$

$\displaystyle du=1$

$\displaystyle v=\frac{2^s}{\ln{2}}$

And I get:

$\displaystyle s\ln{2}-\int{\frac{2^s}{\ln{2}}}$

I have no idea what to do with that integral
