Question

Express the complex number in trigonometric form.
-3 + 3sqroot(3i)

Answer 1

This is the expression? With the i under the root?
\[\Large\bf\sf -3+3\sqrt{3i}\]

Answer 2

correct

Answer 3

Hmm I dunno :(

Answer 4

it should be\[-3+3\sqrt{3} *i\]

Answer 5

similar to standard form
x+y i
here
x=r*cos(theta)
y=r*sin(theta)
and
\[r=\sqrt{x^{2}+y ^{2}}\]

Answer 6

Yes,
\[\Large\bf\sf -3+\left(3\sqrt{3}\right)\mathcal i\]makes much more sense as it has a special angle representation in polar.
But I verified it with the asker, he seems to think the i is under the root.

\(\Large\bf\sf -3+3\sqrt{3i} \) `does` have a polar representiation, I'm just not sure how to find it.
