As x is a pure real number, but y only with imaginary part. 3 q; y. G4 d- f* h; G# bSo if want to compare these two numbers, it should compare there magnitude. 5 v9 o3 n, D5 B1. x -> 0+0i ( @, O/ H# X) o1 f8 r! ntvb now,tvbnow,bttvb2. y -> 0+1i * M9 y% b* J) N.

Magnitude of x is |√(0^2 +0^2)| = 0tvb now,tvbnow,bttvb; Z) c( D/ b9 R( J/ U
Magnitude of y is |√(0^2+1^2)| = 1 5 v7 [7 `2 h3 S3 b公仔箱論壇 G1 J* A" v$ T% U8 ^
So, the magnitude of y >x作者: rubykwok 時間: 2013-1-6 06:50 PM
