integration help

Hi I need help with this integration question,

integrate (3x+1)/(2x+1) wrt x

I tried integrating by parts but not able to solve it, can anyone help? thanks in advance.

long division?

1. Long division first, get 3/2 -(1/2)(1/(2x+1))

2. Integrate to get (3/2)x -(1/4)lnl2x+1l + constant

thanks !

hi need help again

how to integrate 1/(1+cos2x) wrt x ??

Hi,

Consider the result cos 2x = 2(cos x)^2 - 1.

Thanks.
