Write the complex number in the form a + bi. 6(cos 330° + i sin 330°)

The complex number  6(cos 330° + i sin 330°) in the form of a+bi is:

3√3-3 i

Step-by-step explanation:

6(cos 330° + i sin 330°)

= 6(cos(360°-30°)+ i sin(360°-30°))

=6(cos30°- i sin30°)   (since, 360°-30° lies in fourth quadrant and cos is positive there and sin is negative)

=

Distributing 6, we get

=3√3-3 i

Hence, the complex number  6(cos 330° + i sin 330°) in the form of a+bi is:

3√3-3 i

the least common denominator is 40
