Question

What is 2(cos330+isin330)?

Answer 1

$\huge\underline\mathbb{ANSWER}$

2 times the quantities in bracket, giving:

2[cos(330°)+ isin(330°)] =

2 cos(330°) + 2i sin(330°) =

= 1.732 − 1i

You can now plot again your complex number with 1.732

on the REAL axis (Re) and −1

on the IMMAGINARY axis (Im):
