Convert to Rectangular 5(cos(pi/2)+isin(pi/2))

$5 (\cos (\frac{π}{2}) + i \sin (\frac{π}{2}))$

Step 1

Simplify each term.

The exact value of $\cos (\frac{π}{2})$ is $0$ .

$5 (0 + i \sin (\frac{π}{2}))$

The exact value of $\sin (\frac{π}{2})$ is $1$ .

$5 (0 + i \cdot 1)$

Multiply $i$ by $1$ .

$5 (0 + i)$

Step 2

Add $0$ and $i$ .

$5 i$
