Question

$$\frac { 1 } { i }$$

Evaluate

$-i$

Solution Steps

Multiply both numerator and denominator by imaginary unit $i$.

$$\frac{i}{1i^{2}}$$

By definition, $i^{2}$ is $-1$. Calculate the denominator.

$$\frac{i}{-1}$$

Divide $i$ by $-1$ to get $-i$.

$$-i$$

Real Part

$0$

Solution Steps

Multiply both numerator and denominator of $\frac{1}{i}$ by imaginary unit $i$.

$$Re(\frac{i}{1i^{2}})$$

By definition, $i^{2}$ is $-1$. Calculate the denominator.

$$Re(\frac{i}{-1})$$

Divide $i$ by $-1$ to get $-i$.

$$Re(-i)$$

The real part of $-i$ is $0$.

$$0$$
