So far we have looked at measuring coordinates with conventional methods and using gravity field. Part I: Polar Coordinates. Objectives. Objectives: Know how to convert between polar and Cartesian coordinates and how to sketch functions in polar coordinates. Corresponding Sections in Simmons 16.1,16.2,16.3. MATH 1112. S. F. Ellermeyer. Rectangular vs. Polar Coordinates. Rectangular coordinates are the usual (. x,y. ) coordinates.. Polar coordinates are (r,. θ. ) coordinates – where . θ. is the directed angle measured in the usual way and r is the directed distance from the origin to the point in question. “Directed distance” means that we travel in the direction of the terminal side of .

To find the distance between two points, count the units between them.. There is another way to find the distance, without counting units.. First, we need to know the following things:. Introduction. Polar coordinates are an alternative system to Cartesian coordinates. Some processes and equations involving the Cartesian system can become very complicated. You can simplify some of these by using Polar coordinates instead.
