Here are the answer options:
A. 2(cos90º + i sin90º)
B. 2√2(cos150º + i sin150º)
C. 2(cos7$${\mathtt{\pi}}$$/4 + i sin7$${\mathtt{\pi}}$$/4)
D. 2√2(cos7$${\mathtt{\pi}}$$/4 + i sin 7$${\mathtt{\pi}}$$/4)
i think its either C or D but im not sure. Thanks guys! ;)
The angle is anti-clockwise from the positive x axis so that is 7pi/4
The distance out the front is from the origin so it is $$\sqrt{4+4}=\sqrt{8}=2\sqrt2$$
so the answer is D
