Presentation Transcript

  1. Bellwork Convert to rectangular coordinates: Convert to polar coordinates:

  2. Plot These Points:

  3. 11.1b Polar Coordinates Graphing – Cardiods and Limacons

  4. CARDIOIDS:

  5. 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.

  6. r θ Name____________________ Symmetry: _________________ Max: _____________ Min: _____________ y or x-int(s): _____________________

  7. r θ Name____________________ Symmetry: _________________ Max: _____________ Min: _____________ y or x-int(s): _____________________

  8. 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.

  9. LIMACON:

  10. r θ Name______________________ Symmetry:_____________ Loop? ____________ Max: _______________ Min: _______________ y or x-int(s): _____________________
