As x is a pure real number, but y only with imaginary part.tvb now,tvbnow,bttvb" g% o+ x( Z3 v2 G, U4 O) ?
So if want to compare these two numbers, it should compare there magnitude.公仔箱論壇3 L- R3 Z3 L) ]% |
1. x -> 0+0i

Magnitude of y is |√(0^2+1^2)| = 13 W, T+ O0 o+ E+ F& Q

So, the magnitude of y >x |
