given
Z1= 2-2i Z2= (square root of 3)-i
i need help finding the answers for
Z1*Z2 and Z1/Z2
needs to find polar complex
The polar form that lanzailan gives is r and the angle (in degrees). For problems like this it is better to give the angle in radians: These complex numbers can be written as $\displaystyle 2\sqrt{2}(cos(\frac{\pi}{4})- sin(\frac{\pi}{4})$, $\displaystyle 2(cos(\frac{\pi}{6})+ sin(\frac{\pi}{6})$, or, equivalently, $\displaystyle 2\sqrt{2}e^{i\frac{\pi}{4}}$ and $\displaystyle 2e^{i\frac{\pi}{6}}$.
To find the product of two complex numbers, in complex form, you multiply the moduli (r values) and add the angles. To divide, divide the moduli and subtract the angles.
