As x is a pure real number, but y only with imaginary part.os.tvboxnow.com' r( u7 s& r6 d% a- B
So if want to compare these two numbers, it should compare there magnitude. 3 y" c3 j/ P" S. `os.tvboxnow.com1. x -> 0+0i 5 D }2 p: b' f3 a; F# A2. y -> 0+1i ! @7 W7 y1 t7 B' }& n. h% t( i/ c' ]$ u! M
Magnitude of x is |√(0^2 +0^2)| = 0 0 ^6 d* C3 R9 b1 zMagnitude of y is |√(0^2+1^2)| = 1& n) ~* v: m! I
tvb now,tvbnow,bttvb, r1 f: i. C- n* P. W
So, the magnitude of y >x作者: rubykwok 時間: 2013-1-6 06:50 PM
