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 plot of the three points from Question 1 of the 'Complex Roots with De Moivre's Theorem' worksheet. Use the slider to raise them to the power of n and see what happens. Use the values n = 2, 3, 4 to answer the questions in the worksheet. If you right-click on a point and select 'Trace on', you will be able to see where it goes more easily.
