#x = -1 * cos ((11pi)/12) )= color (green)(0.9659)#

#y = -1 * sin ((11pi)/12) )= color (red)(-0.2588#

We can use the following formulas to convert polar to Cartesian coordinates.

#x = r cos theta, y = r sin theta #

#Given : [r,theta] = [-1, (11pi)/12]#

#x = -1 * cos ((11pi)/12) )= color (green)(0.9659)#

#y = -1 * sin ((11pi)/12) )= color (red)(-0.2588#

#tan theta = tan ((7pi)/12) = -3.732#
