- Over the next few sections, we will be learning about
**power series**,**Taylor series**, and**Taylor polynomials**. - You might be asking "why are we learning about these things? And how does this relate to all of the things we have learned about in the past 5 sections?"
- Let's start with an example that will hopefully motivate our discussion over the next 3 sections.
- Take a few minutes to compute the following:

\(\displaystyle \int e^{-x^2} \, dx\).
