As x is a pure real number, but y only with imaginary part.6 ?" v9 t/ N* B/ Y9 n/ M$ A& t) t
So if want to compare these two numbers, it should compare there magnitude., Q0 Z( p0 F6 }) \5 R$ L
1. x -> 0+0i公仔箱論壇. R0 B* u% k% p- Q2 q# j
2. y -> 0+1itvb now,tvbnow,bttvb: k& g, r4 }# \7 V8 I! z
& S' l4 b) C" q" Twww.tvboxnow.comMagnitude of x is |√(0^2 +0^2)| = 0tvb now,tvbnow,bttvb& H x6 C2 r+ I. _& K
Magnitude of y is |√(0^2+1^2)| = 1

So, the magnitude of y >x |
