π: Ctrl+P or Alt+P or pi.
: Ctrl+8 or Alt+8 or infinity.
θ: Ctrl+T or Alt+T or theta. You can also use x or t instead of θ in polar mode; they will be replaced by θ when you press Draw Graph or Enter on the keyboard.

Using your mouse: change the scales and labelsNew, translate the origin and rotate the axes

Example - Parametric Equations of 2D Curves:

p(t) = (4sin(t), 3cos(t))  ellipse (Cartesian)

p(t) = (2tcos(t^2),3t^2) domain=(-1,1)  Graph it! (Polar)

p(t) = (4cos(3t),5sin(9t))  Graph it! (Polar)
