De Moivre's Theorem

Hold down the shift key and click and drag on the window to move the axes. Hold down the shift key and scroll down/up to zoom in/out. Here is a complex number, z, given in polar form. Use the sliders on the left to see how z changes as you change the modulus and argument (in radians), and then use n to see what happens when you raise z to the power of n.
