Hey guys i keep getting stuck with this:
integral of ( ln(2x+1)dx)
im supposed to use by parts
heres what i have done
u=ln(2x+1)
du=2/2x+1
dv=dx
v=x
then i apply the formula uv-vdu
and i end up with another integral I am supposed to use by parts for:
integral of(2x/2x+1 dx)
heres what i have done for that integral
u=2x
.5du=dx
dv=1/2x+1
v=ln(2x+1)
then i apply the formula again, and since i have the same integal i stared wit, i add it to the lef side etc etc... but i don't get the correct answer...what does it look lie I am doing wrong?
