should be \[2\sqrt{2}(\cos \pi/4 + i \sin \pi/4)\]

but i don't see it anywhere

The magnitude is \[ \sqrt{\frac{1}{2^2}+\frac{1}{2^2}} =\frac{\sqrt{2}}{2}\]

thanks, I dont either. Like I said, not sure how to get to the answer
phi
  • phi
The way you get the answer is look at amistre's plot. Find the length of the hypotenuse using pythagorean theorem use inverse tangent of opposite/adjacent to find the angle alpha
phi
  • phi
the answer is \[ \frac{\sqrt{2}}{2}(cos(\frac{\pi}{4}) + i sin(\frac{\pi}{4}) \]
