6(cos 330° + i sin 330°)

Answer 1

If somebody could just walk me through it please and thank you

Answer 2

Find cos330 and sin300, then expand.

Answer 3

6 ( (.8660254038) + i (-.5))

Answer 4

5.196152423 - 3i

Answer 5

use the exact value, you should be able to find this at this point
\[cos(330) = \frac{\sqrt{3}}{2}\]

Answer 6

so then it's\[6(\sqrt{3}/2 +-.5i)\]

Answer 7

Yes. Good job.

Answer 8

Expand it though.

Answer 9

\[3 \sqrt{3} - 3i\]

Answer 10

Yeah.

Answer 11

yeah, thank you all!
