Q. The additive inverse of $1 - i$ is
A) $0 + 0i$
B) $- 1 + i$
C) $- 1 + i$
D) None of these
Explanation
(b)
If $z = x + iy$ is the additive inverse of $1 - i$, the
$x + iy + (1 - i) = 0$
$\Rightarrow \ \ \ \ x + 1 = 0,\ \ \ y - 1 = 0$
$\Rightarrow \ \ \ x = - 1,\ \ \ y = 1$
Here required additive inverse is $- 1 + i$
