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 \(\pi\)

Best ResponseYou've already chosen the best response.0I don't think it's going to let me take it as a decimal though, especially since is a irrational, nonrepeating decimal: http://www.wolframalpha.com/input/?i=tan^%281%29+%285%2F3%29

Best ResponseYou've already chosen the best response.0Actually that's fairly close annas The actual value is 1.030376827... (radians) \(\frac{\pi}{3}\) is 1.047197551... (radians)

Best ResponseYou've already chosen the best response.0Let me see if it takes it after I do the rest of the problem, if it does, you getz a cookie :3

Best ResponseYou've already chosen the best response.0\[\frac{\pi}{3} \rightarrow \frac{5\pi}{3}\] Yes? And... (\(\large\sqrt{34},\frac{2\pi }{3}\)) is the valid r<0 value, yes?

Best ResponseYou've already chosen the best response.0I don't know what they were expecting here. It's not quite a 345 triangle here, the 5 is on the opposite side, not the hypoteneuse

Best ResponseYou've already chosen the best response.0*idea* I'm going to try 180/\(\pi\) to convert and see if I can recognize it
