As x is a pure real number, but y only with imaginary part.4 g4 B- c4 H4 o1 V/ g' p3 @
So if want to compare these two numbers, it should compare there magnitude.1 n5 J* Y: B5 z0 O/ c. x+ m
1. x -> 0+0itvb now,tvbnow,bttvb8 p& w7 F) a& Z1 A
2. y -> 0+1i0 A. o0 O3 H( _, {
9 |: Y( X! u8 ~9 ]% g- ?# B
Magnitude of x is |√(0^2 +0^2)| = 0" P2 T3 M/ X2 [- m( v
Magnitude of y is |√(0^2+1^2)| = 1: w+ B) ~9 |) j: {$ y2 j
; o+ m) M* ]3 {5.39.217.76So, the magnitude of y >x |
