Question

Convert the complex number 3 + 3i into its polar representation.

Answer 1

A. 2 sqrt3 (cos(60) + isin(60))
B. sqrt3 (cos(225) + isin(225))
C. 3(cos(135) + isin(135))
D. 3 sqrt2 (cos(45) + isin(45))

Answer 2

I think it is A but I am not sure

Answer 3

For a complex number a+bi the magnitude is found by sqrt(a^2 +b^2) the angle is found by tan(theta) = b/a

|z|-->Magnitude
θ-->angle
z=|z|(cos(θ)+isin(θ))
