Graphing Polar Equations :

The most basic method of graphing polar equations is by plotting points and doing a quick sketch. Graphing polar equations is a skill that requires the ability to plot points and sometimes recognize a special case of polar curves, such as cardioids, androses and conic sections. However, we need to understand the polar coordinate system and how to plot points for graphing polar equations.

How to sketch a simple polar curve by plotting points.

Graphing polar curves can be tricky. This video looks at graphing some of the basic ones first.

This video shows the common trick of writing our polar equation in cartesian form so that we can (hopefully) recognize it as a common graph. In this case, our polar equation simply turns out to be a circle.

Just another example of taking a polar equation and putting it in cartesian form so that we can graph it more easily.

Graphing Special Polar Equations, Ex 2.

Many polar graphs have 'petals'. How many petals will a graph have? This problem addresses that question.
