The xcoord
function returns the x coordinate of the specified polar coordinates. The first argument is the distance from the origin and the second argument is the angle from the positive x-axis in radians.
The formula for the xcoord
function is:
xcoord
(r, th) = r*cos(th)
The xcoord
function is faster and more accurate than using the above formula.
