Trigonometry, Polar Coordinates, & Complex Numbers

Course Description

In this series, the very helpful and fun math teacher Mr. Tarrou teaches students an entire course on trigonometry from start to finish, and on top of that, provides a comprehensive and easy to understand introduction to polar coordinates, vectors, and complex numbers. His videos are friendly, easy to understand, entertaining, and very well organized, all thanks to Mr. Tarrou great dedication to teaching and enthusiasm for mathematics.

Trigonometry, Polar Coordinates, & Complex Numbers
Trigonometry is not the sole topic tackled in this high school course. Mr. Tarrou also covers polar coordinates and complex numbers. In this picture, Mr. Tarrou shows how to graph Rose Curves in Lecture 45: Graphing Polar Equations.
