[sDIY] ot integrating ln(x)

[Paul van Nugteren]

My stupid maths textbook doesn't explain very good how to integrate lnx. It
just said "prove that f(x)->lnx , => F(x)-> xlnx-x. I proved it by diff Fx
but if you diff x it becomes 1 which you "can't see" because 1 times 45 =
45.

So can anyone give me the formula for integrating lnx (not using x but
ln(f(x)). MC?

Thanks sorry for the OT of this but I'm really bothered by this...
