The point A is on the circumference of a circle of radius R units lying in the xy plane and centered at O (the origin). The ray OA makes an angle 110° with the +x-axis.
(i) Find the x & y co-ordinates of the point A, in terms of R and the trigonometric ratios of 110°.
(ii) If B is a point diametrically opposite to A, find the x & y co-ordinates of the point B.
