As x is a pure real number, but y only with imaginary part.tvb now,tvbnow,bttvb9 u! m0 C2 C( h
So if want to compare these two numbers, it should compare there magnitude.; I) R& R! g% T3 L8 O9 ?
1. x -> 0+0i

Magnitude of y is |√(0^2+1^2)| = 1www.tvboxnow.com9 t9 k- G# f, F Y

So, the magnitude of y >x |
