Consider the point in the plane given by polar coordinates $(r,)=(2,\frac{}{3}).$

$($a$)$ Express this point in polar coordinates where $r=2,$ but $\frac{}{3},$ if possible.

$($b$)$ Express this point in polar coordinates where $=\frac{}{3},$ but $r2,$ if possible.

$($c$)$ Express this point in polar coordinates where $r2$ and $\frac{}{3},$ if possible.
