1just draw an auxillary circle for that ellipse,& join the centre of ellipse to the parametric point(@) on that ellipse.....extend the line so that it meets the auxillary circle,
;that point will be parameter of the circle(Rcos@,Rsin@)
& it will form an angle "@"(eccentric angle) with the positive X axis
