If we determine the number's magnitude \displaystyle r and argument \displaystyle \alpha , we can write its polar form using the formula
| \displaystyle r(\cos\alpha + i\sin\alpha)\,\textrm{.} |
Because the number lies on the imaginary axis, it is possible to write its magnitude and argument directly.
The polar form is
| \displaystyle 11\Bigl(\cos\frac{3\pi}{2} + i\sin\frac{3\pi}{2}\Bigr)\,\textrm{.} |
