May 4, 2013 · 2 Another Wikipedia article of relevance is Characterizations of the exponential function. Which characterization is most appropriate to take to be the definition depends on the context.

Aug 23, 2023 · For every real number $x$, we define the natural exponential function to be $e^ {x} = \exp (x)$. Where $\exp$ denotes the inverse function of $\ln$, and $e$ is a number such that $\ln (e) …

Jan 3, 2023 · My question : (1) Do these definitions exhaust the ways the exponential function can be defined? (2) Are these definitions actually different at least conceptually ( though denoting in fact the …

So here's my proof, using only the definition of the exponential function and elementary properties of limits. We use the following definition of the exponential function:

Aug 22, 2021 · Finding exponential function limit definition from definition of e Ask Question Asked 4 years, 3 months ago Modified 2 years, 9 months ago

Feb 16, 2013 · Just a quick note on the comment, there is no need to assume that the exponential is differentiable. Simply define the exponential function $\exp (x) = \sum_ {i=0}^ {\infty}$ and all the …

Mar 5, 2023 · We can solve this limit by using the natural logarithm and the limit definition of the exponential function. Let's begin by taking the natural logarithm of the expression inside the limit:

Aug 7, 2020 · By definition, an exponential function is where the independent variable (the x-value) is the exponent. While you're not wrong in this respect, this only really holds if the function is in its …

You should look at the Wikipedia article about characterizations of the exponential function; it has five. As for your question about whether a function can be expressed as a series or not, to answer it I …

Preface: The best first definition of e is one that nobody has yet given in this thread, namely, that it is the base such that the corresponding exponential function has a slope of unity at 0.
