Solve 1-i^2/i

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

Evaluate

$$-2i$$

Solution Steps

Calculate i to the power of 2 and get -1.

$$\frac{1-\left(-1\right)}{i}$$

The opposite of -1 is 1.

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

Add 1 and 1 to get 2.

$$\frac{2}{i}$$

Multiply both numerator and denominator by imaginary unit i.

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

Divide 2i by -1 to get -2i.

$$-2i$$

Real Part

$$0$$

Solution Steps

Calculate i to the power of 2 and get -1.

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

The opposite of -1 is 1.

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

Add 1 and 1 to get 2.

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

Multiply both numerator and denominator of \frac{2}{i} by imaginary unit i.

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

Divide 2i by -1 to get -2i.

$$Re(-2i)$$

The real part of -2i is 0.

$$0$$
