Answer 4

you need to know your unit circle

Answer 5

For a complex number x+yi to convert to polar
r=sqrt (x^2+y^2)
θ=arctan (y/x)

r (cosθ+isinθ)

Answer 6

180 deg = pi

Answer 7

the answer looks like its c.

Answer 8

z=−4i
z=4⋅(cos 270+i⋅sin 270)
3pi/2 = 270 degrees

Answer 9

no

Answer 10

oh

Answer 11

thea is not a 270

Answer 12

cos(pi), sin(pi)

Answer 13

@Austin6i6 would the answer be d.-4(cos0+i sin0)?

Answer 14

No, i believe it is A. based on the unit circle
