WebThe polar form of complex numbers emphasizes their graphical attributes: \goldD {\text {absolute value}} absolute value (the distance of the number from the origin in the complex plane) and \purpleC {\text {angle}} angle (the angle that the number forms with the positive Real axis). These are also called \goldD {\text {modulus}} modulus and ... Webas follows. One can easily see that multiplication by ei rotates the point z= 1 along the unit circle by an angle , taking (in terms of real coordinates) (1;0) !(cos ;sin ) This is also true for the point z= i, which gets taken to i(cos + isin ) = sin + icos . In terms of real coordinates on the plane, this is (0;1) !( sin ;cos )
