Hi there,
I am not too sure how to go about the question 'integrate xlnx dx'
the answer is meant to be (x^2lnx)/2-x^2/4+C
could someone help please?
Usually integration by parts with lnx and some polynomial term in x, you use lnx term to be u, so that, differentiating it cancels other term (more of an exam tip).
