Question

Find the polar coordinates (-4√(3),-4) for r > 0

Answer 1

\[x = rcos \theta, y = rsin \theta\]
\[4\sqrt{3} = rcos \theta\]
\[-4=rsin \theta\]

From that point you can get theta. Then... think a bit more to get r.

Answer 2

So rsin theta equals -4?

Answer 3

Yes, the you need to do: -rsin theta = 4 = (rcos theta)/sqrt(3)

Answer 4

tan theta equals....
