As x is a pure real number, but y only with imaginary part.5.39.217.77:8898" j" @+ K: P! J1 s& |8 ]
So if want to compare these two numbers, it should compare there magnitude.; |: ]; H. M, t. B: b

Magnitude of x is |√(0^2 +0^2)| = 0 , ~4 m1 j* G n1 s; T3 TTVBNOW 含有熱門話題,最新最快電視,軟體,遊戲,電影,動漫及日常生活及興趣交流等資訊。Magnitude of y is |√(0^2+1^2)| = 1 3 I& F9 f! |0 t( x2 N' J公仔箱論壇 w. D) E/ x. K: d; U
So, the magnitude of y >x作者: rubykwok 時間: 2013-1-6 06:50 PM
