Polar Graphing: Circles


Circles with center at origin

​Desmos File: Graphing r = a
Center AT origin (degrees)

click on lower right corner to use this online graphing calculator
  • this allows you to plot circles with center at origin on the polar coordinate plane
  • angles are measured in degree measures 

​Desmos File: Graphing r = a
Center AT origin (radians) 

click on lower right corner to use this online graphing calculator
  • this allows you to plot circles with center at origin on the polar coordinate plane
  • angles are measured in radian measures 

Circles with center on x axis

​Desmos File: Graphing r = 2a cos(θ)
Center RIGHT of origin (degrees)

​click on lower right corner to use this online graphing calculator​​
  • this allows you to graph circles on the polar coordinate plane 
  • the angles are measured in degrees

​​Desmos File: Graphing r=2acos (θ)
Center RIGHT of origin (radians)

click on lower right corner to use this online graphing calculator​​
  • this allows you to graph circles on the polar coordinate plane
  • the angles are measured in radians

​Desmos File: Graphing r = -2a cos(θ)
Center LEFT of origin (degrees)

​click on lower right corner to use this online graphing calculator​​
  • this allows you to graph circles on the polar coordinate plane 
  • the angles are measured in degrees

Desmos File: Graphing r = -2acos (θ)
Center LEFT of origin (radians)

click on lower right corner to use this online graphing calculator​​
  • this allows you to graph circles on the polar coordinate plane
  • the angles are measured in radians

Circles with center on y axis

​Desmos File: Graphing r = -2a sin(θ)
Center ABOVE origin (degrees)

click on lower right corner to use this online graphing calculator​​
  • this allows you to graph circles on the polar coordinate plane 
  • the angles are measured in degrees

​​Desmos File: Graphing r=2asin (θ)
Center ABOVE origin (radians)

click on lower right corner to use this online graphing calculator​​
