As x is a pure real number, but y only with imaginary part.2 k) @( F; m- z
So if want to compare these two numbers, it should compare there magnitude.tvb now,tvbnow,bttvb( j- E, W; ]" Q" N2 W& R1 j; a, j- Q
1. x -> 0+0i \$ R* R0 p. U
2. y -> 0+1i

Magnitude of x is |√(0^2 +0^2)| = 0' m; w, G4 k6 M1 M: E
Magnitude of y is |√(0^2+1^2)| = 1
3 P( M% h' ^$ X' ^( i/ a6 l2 ?0 i$ h1 ]9 a: X
So, the magnitude of y >x |
