11.1b Polar Coordinates Graphing – Cardiods and Limacons



Cardiod summary
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.

Limacon summary
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.
