Suppose [math]p[/math] and [math]q[/math] are multiplied by [math]a[/math], where will you see the products? What may happen to the picture of the products [math]ap[/math] and [math]aq[/math] are still the base of that picture?[br][br]Make a guess. Then check by clicking the object 'pic2' on the left. [br][br]Drag the three complex numbers to test the relation you are considering. Would this help you to see what happens when complex numbers are multiplied?
