Division of polar-form complex numbers is also easy: simply divide the polar magnitude of the first complex number by the polar magnitude of the second complex number to arrive at the polar magnitude of the quotient, and subtract the angle of the second complex number from the angle of the first complex number to arrive at the angle of the quotient: Figure 1.18 shows all steps. ]JIMNjKg-70GOcbB ;?R]J6#@+6Z,X,u#5+g&oSYNWDm^SA(OQK'#BG8tl)gJ*p-?W*'C$V;rca+Z__J1kpBk#FoSg_*\9Dm?UBs\*7OT4u7Q^ asked Mar 1, 2013 in BASIC MATH by Afeez Novice. )EnDnlTAg:@fVPV)cUF-*lb$'FNB3PNhF]X\+js+DWIPQIQZ+f_D1.<7)a%584X) 6Q#jh;gt0e;lW?QB@Ik/)9>Ze*?&F1W9])!5+Z$i^!ue54e^]qM>mX`(P=sASL'E) KS_A,LG\U,W($P=Mhct@0Lsf(N=_-XK?
