# Please confirm simple integration watch

1. Okay, we have this:

But I thought log(a) + log(b) = log(ab), not log(a/b)

Or am I being really silly?

Thanks.
2. If you differentiate you get (since the coefficient of N is -1), hence the result... however it's not quite right, since you should have a constant of integration there (unless the constant on the RHS came from another integral).

I think it looks like a differential equation question, where they have to solve it. It also looks like they have gathered the constants, but didn't change the letter (which is what generally occurs).

5. Pah, yea, realised it the second I posted it. Hmmm.... I'm not thinking right today. Thanks all.

Yea, the rhs came from another integral.
