10.3: Taylor Series


So, in 10.1 [11.1], you learned about Taylor (and MacLaurin) Polynomials*, then in 10.2 [11.2], we looked at what power series are, and how to find the radius of convergence.

*As prevously mentioned, MacLaurin Series are just a special case of Taylor Series. with the series centered at x = 0 which is by far the most common situation for any power series; i.e., being centered at x = 0.

In this section, we'll put those two concepts together to form Taylor Series, which are a specific type of power series.
