Rainy Saturday


Reminding myself how changing bases for logarithms is done.
The example is the number 12, which has a smaller log base_10
than base_e. Multiplied by ln(10), gives ln(12). Checked it by
requesting e^to that value.

So what does e^x as a quotient do.

e^x can be neatly integrated, but 1/e^x cannot because of an asymptote.


Below, a Desmos utility, set from 1 to 10.
