QuestionConvert the complex number to polar form: $4-4 i$

Studdy Solution
Express the complex number in polar form using the magnitude and argument:
The polar form is given by:
$$4 - 4i = 4\sqrt{2} \left( \cos\left(-\frac{\pi}{4}\right) + i\sin\left(-\frac{\pi}{4}\right) \right)$$
The polar form of the complex number $4 - 4i$ is:
$$4\sqrt{2} \text{cis} \left(-\frac{\pi}{4}\right)$$
