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.[br][br]Here is a complex number, [i]z[/i], given in polar form. Use the sliders on the left to see how [i]z[/i] changes as you change the modulus and argument (in radians), and then use [i]n[/i] to see what happens when you raise [i]z[/i] to the power of [i]n[/i].
