As x is a pure real number, but y only with imaginary part. p+ s' G1 S9 {8 B6 F# v2 C# a* R5.39.217.77So if want to compare these two numbers, it should compare there magnitude.公仔箱論壇. q- S7 q4 O' C9 C
1. x -> 0+0i公仔箱論壇& q$ K- a2 ~ r! w/ Y
2. y -> 0+1i5.39.217.774 [. r, a0 h) A2 q
tvb now,tvbnow,bttvb. G$ y" p2 r- Z; e9 u
Magnitude of x is |√(0^2 +0^2)| = 0 % l( \% U9 E6 }6 k6 P8 p) PMagnitude of y is |√(0^2+1^2)| = 1 7 c0 a( T; Z; Q' k! `5.39.217.77& h4 I) G6 X/ }. T* o
So, the magnitude of y >x作者: rubykwok 時間: 2013-1-6 06:50 PM
