As x is a pure real number, but y only with imaginary part.
7 L, }) @" c/ f) K9 l) mSo if want to compare these two numbers, it should compare there magnitude.

Magnitude of x is |√(0^2 +0^2)| = 0( ?+ i* G" l- N w
Magnitude of y is |√(0^2+1^2)| = 1公仔箱論壇) E( v0 w) {' o5 D/ K1 T

So, the magnitude of y >x |
