Dear Miss Ong,

How do I integrate x ln x ?

May I know the reverse rule for product rule ?

Thank you ^^ Really appreciate the advice.

Cynthia,

I think this is a question from 2011 or 2012 GCE O-Level Additional Maths.

There's no reverse rule for product rule.

The main concept for such question is

Given: d/dx (apple) = orange

Integrate (orange) = [apple]

Cynthia says

Yes, the same question appeared in other years' paper as well.

May I know what are the method for integrating part by part ? Really wish to salvage the 3 marks as I think that question may appear in exam...
