$theta = alpha$ is the equation of the radial line,from pole, in that

direction.

The radial line is in $[ Q_1 Q_2 Q_3 Q_4 ]$ ,

if $alpha in [ Q_1 Q_2 Q_3 Q_4 ]$ , respectively.

Here, it is in $Q_1$ , wherein both $x and y >= 0$ .

The slope of this line is $tan ( 30^o ) = 1/sqrt3$ and the Cartesian

equation is

$y =1/sqrt3 x, x >=0 and y >= 0$ , See graph.
graph{y-x/sqrt3 =0[0 20 0 10]}
