Hello, Janu42!
You never did write it in polar form . . .
The triangle looks like this:Convert into polar form.Code:_ 3√3 * - - - - * * θ | * |9 r * | * | *
On the graph, we see that the angle is
Therefore, the polar form is:
. .
This makes no sense to me. I definitely think I'm doing it right.
Convert 3sqrt(3) - 9i into polar form.
Every time I do it, I get 6sqrt(3)(1/2 - .....) The second part doesn't work.
What am I doing wrong?
EDIT: Bonus Question:
Prove there is no field F such that R is not a subset of F which is not a subset of C. (R is the real numbers and C is the complex numbers, sorry I don't know how to do the math writing on here well yet.)
