Talk:Sum of Logarithms

Do you want to reference the fundamental theorem of calculus when you say $\forall x > 0: f^{\prime} \left({x}\right) = \frac 1 {xy} y - \frac 1 x$ since you're differentiating an integral? --Cynic (talk) 03:49, 20 January 2009 (UTC)

Good call. --Matt Westwood 06:34, 20 January 2009 (UTC)
