Hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

So as title states, how would one sketch Re(iz) = 3? And an explanation would be splendid.

This is what I thought:

let z = a + bi

i(a+bi) = -b + ai

Therefore: Re(iz) = -b = 3

So Real axis = -3?

Or would it be Real axis = 3

Since iz is an arbitrary complex number and the real part of this arbitrary complex number is 3.
