Taylor series with Python and Sympy: Revised

More than 2 years ago I wrote a short post on Taylor series. The post featured a simple script that took a single variable function (a sine in the example), printed out the Taylor expansion up to the nth term and plotted the approximation along with the original function. As you can see on the right on the “Popular posts” bar, that post is one of the most popular and I’m told it appears among the first results on Google.

The script I wrote originally was a bit clunky, and there surely was room for improvement. Last week I received an email from a reader, Josh, who sent me an improved version of the original post.
