## Calculus Revisited: Complex Variables, Differential Equations, and Linear Algebra

**Calculus Revisited: Complex Variables, Differential Equations, and Linear Algebra (Res.18-008, MIT OCW)**. This consists of
20 video lectures given by Professor Herbert Gross, providing an introduction to Complex Variables, Ordinary Differential Equations
and Linear Algebra. Calculus Revisited is a series of videos and related resources that covers the materials normally
found in freshman- and sophomore-level introductory mathematics courses. Complex Variables, Differential Equations,
and Linear Algebra is the third course in the series, consisting of 20 Videos, 3 Study Guides, and a set of Supplementary Notes.

Part I, Lecture 4 - Sequences and Series |

Herb Gross defines complex valued functions by means of power series expansions. He shows us how the amazing identity of DeMoivre is derived.
