Find the cube roots of 27(cos 330á + i sin 330á). c:

The cube roots are

Step-by-step explanation:

Given the expression 27(cos 330° + i sin 330°)

we have to find the cube roots of the above expression.

By Euler's formula,

We can write

Since, 330°=360°+330°=690° and 330°=2(360°)+330°=1050°

Other two solutions are
