Flashcards What is the $y = x$ equivalent for polar coordinates?? $$ r = \theta $$ What is $x$ in terms of $r$ and $\theta$ for polar coordinates?? $$ x = r\cos\theta $$ What is $y$ in terms of $r$ and $\theta$ for polar coordinates?? $$ y = r\sin\theta $$ What is $r$ in terms of $x$ and $y$ for polar coordinates?? $$ r = \sqrt{x^2 + y^2} $$ What is $\theta$ in terms of $x$ and $y$?
