    Any thoughts? Clearly points on the line y=x must be part of the graph.

    Also note that  \sin(x+2n\pi )=sin(x) where n is an integer.

    As said by B_9710, you have \sin(x)=\sin(x+360n) for n \in \mathbb{Z}

    So y=x+360n is the extension of what notnek said.

    Also realise that \sin(y)=\sin(180k-y) when k\in \mathbb{Z} \setminus 2\mathbb{Z}, so...?

    If you reflect the function y=f(x) in the line y=x, the resulting graph is described by x=f(y). What result do you get if you do this reflection on the function in question?

    What kind of maniac uses degrees as a measure of angle?
