Chapter 5 – Vector Applications

Topic 5.1
Polar Coordinates

Polar Coordinates covers the navigational system using distance and direction from a given point, compared to the Cartesian ‘city grid’ system. Conversions between Polar Coordinates and Cartesian Coordinates are stressed. This lesson prepares students for the study of vectors and these conversion reappear in the lesson on Applications of Vectors.

Equations of r as a function of θ are not discussed here.
