Suppose that $P=(x,y)$ has polar coordinates $(r,\frac{}{12}).$ Find the polar coordinates for the following points if $in[0,2].$

$($Enter all angles in radians.$)$

$($a$)P=(x,-y)$

$($Give your answer in the form $(\text{'}\text{'},\text{'}).$ Express numbers in esact form. Use symbolic notation and fractions where needed$)$

$($b$)P=(-x_2-y_n)$

$($Oive your asswer in the form $({?}^{**}{?}^{**}).$ Byress nambers in canct form. Use symbolic sodation and fractions where meeled$)$
