As x is a pure real number, but y only with imaginary part.tvb now,tvbnow,bttvb( M! h5 ~1 F6 |; E% y1 _
So if want to compare these two numbers, it should compare there magnitude.tvb now,tvbnow,bttvb+ u, _/ U8 t! l* F
1. x -> 0+0i
- b/ B. G. C" y公仔箱論壇2. y -> 0+1i* i; k, u/ \3 z" @. j) P( Q
- O9 e) S3 [7 ~/ j# X
Magnitude of x is |√(0^2 +0^2)| = 0' k9 ]: ~5 D* Z" \" ?* ^6 y! T# O
Magnitude of y is |√(0^2+1^2)| = 1
0 h) o+ Y5 v: y0 S% m
- I- c. x$ b DSo, the magnitude of y >x |
