Well, to be precise, I didn't claim it was a rigorous proof ;) - it's more to gain intuition.

Nifty. More basic, you could also argue multiplying the argument of a log just shifts the curve in the y-axis by the log of the multiplicator: log(b) = log(ab) - log(a), here with constant b = e, a on the x axis.

Nice, but very bourbaki ;) Seems there is no immediate way to visualize this.

Hi, I'm looking for a visual proof log(ab) = log a + log b I've seen diagrams where the values are measured out, but it's not immediately obvious why this holds. Is there an intuitive way to illustrate this? Also, are there other functions with this property.
