What is the trigonometric notation for 3-3(sqrt3i)?
Hmmm. The i is in the sqrt( )? that means the sqrt of the sqrt if -1.
Is this in the complex plane?
I am not certain what you are doing.
the law of cosine. I am stuck on the issue of converting 3-3 sqare root 3i, and am not sure how to do this.
for example square root 3-i = 2(cos 33 + i sin 330)
