Q. The conjugate of a complex number is$\frac{1}{i - 1}$. Then, that complex number is
A) $\frac{1}{i - 1}$
B) $- \frac{1}{i - 1}$
C) $\frac{1}{i + 1}$
D) $- \frac{1}{i + 1}$
Explanation
(d)
Let $z = \frac{1}{i - 1}$
Then, $\overline{z} = \overline{\left( \frac{1}{i - 1} \right)} = \frac{1}{- i - 1} = - \frac{1}{i + 1}$
