Hey all,
i follow my notes from class to integrate x logx dx
and i come up with the answer 1 - log x,
however when i check my answer with Wolframs online integrator, it gets a different answer.
can somebody show me step by step how to do it?
heres what i did,
x logx dx
= x * 1/x - "int" 1/x * 1
= 1 - logx
our class example doesnt have the x on the front, it just has log x dx.
thanks for any help,
Mitch
It would have helped if you showed the complete details of your working (your choice of u and dv etc.) because what little working you've posted is completely wrong.
