Web17 de jun. de 2024 · When I initially created this post, it was never my intention to replace the exponential function exp(x) with Euler’s number E, or en, etc., for values of x ~= 1. In fact, what I thought of was to use a simple notation like E to call Euler’s number rather than having to type exp(1), which as a mathematician I didn’t like much 😊.
