Polar Curve Plotter
To sketch a polar curve, first step is to sketch the graph of r=f(θ) as if they are x,y variables. This will give a way to visualize how r changes with θ.
The information about how r changes with θ can then be used to sketch the graph of the equation in the cartesian plane.
Drag the slider at the bottom right to change the value of θ and watch the curve be drawn.
