## 11.1b Polar Coordinates Graphing – Cardiods and Limacons

### CardiodSummary

• To Graph we need to:

• Find the max value of the function

• It will always pass thru the origin.

• Identify the symmetry of the function.

### LimaconSummary

• If “a” is larger there is NO LOOP

• If “b” is larger there is a LOOP

• If there is a loop the graph passes through the origin.

• How do we start the graph:

• Begin by finding the max and min value of the function.

• Identify the symmetry of the function.
