Answer
$\left( {x,y} \right) = \left( {0.0187,1.7319} \right)$
Work Step by Step
$$\eqalign{
& \left( {\underbrace {\sqrt 3 }_r,\underbrace {1.56}_\theta } \right){\text{ }} \cr
& \left( {\sqrt 3 ,1.56} \right) \cr
& {\text{Find the rectangular coordinates }}\left( {x,y} \right) \cr
& x = r\cos \theta ,{\text{ and }}y = r\sin \theta ,{\text{ then}} \cr
& x = \sqrt 3 \cos \left( {1.56} \right) = 0.0187 \cr
& y = \sqrt 3 \left( {1.56} \right) = 1.7319 \cr
& {\text{Therefore}}{\text{, the rectangular coordinates are:}} \cr
& \left( {x,y} \right) = \left( {0.0187,1.7319} \right) \cr
& \cr
& {\text{Using Geogebra we obtain}} \cr
& {\text{Graph}} \cr} $$
