Applications of Power Series (Maclaurin Series)

Calculus 2 video that explains some power series applications: power series representation of functions, power series integration, and power series approximation (Maclaurin series approximation). We work several examples of using Maclaurin series to approximate a value, derive a similar series more easily, and approximate a definite integral that we could not normally integrate.
