Converting Cartesian coordinates into polar coordinates.
(x,y) = (3,-5)
(r,\(\theta\)) = (\(\sqrt{34}\),???)
\(r=\sqrt{(3)^2+(-5)^2}=\sqrt{9+25}=\sqrt{34}\)
\(\theta = tan^{-1}(\frac{(-5)}{(3)})=???\)
My answer needs to be in radians an I'm not seeing how the unit circle is going to be of much help here. It's not a nice angle like \(\frac{\pi}{2}\), \(\frac{\pi}{3}\), \(\frac{\pi}{4}\), \(\frac{\pi}{6}\), or \(\pi\)
