The theta
function returns the angle, in radians, of the specified coordinates from the positive x-axis. The first argument is the x coordinate, and the second argument is the y coordinate.
This function is similar to the atan2
function, but the arguments are in opposite order. It is also similar to the arg
function, but it takes two arguments rather than one.
