I’m not sure I’m completely happy with that explanation. They use the result that ln(1+x) is very close to x when x is small. This is due to the Taylor series expansion of ln(1+x) (edit:or simply on looking at the ratio of the two and using L’Hospital’s rule), but if one hasn’t had calculus, that claim is going to look like magic.
