Why 360 degrees? Why 2pi radians?
Change the unit of an angle by sliding the 'a' slider.
Or click the buttons.
You can adjust the x-scale by shift-dragging the x-axis.
Click the check box to see the gradient function.
When is the gradient function most like the original function?
Is there a 'best' unit for angles?
