an ellipse is a circle in a drawing. E.G. at the top of a flower vas.
That's the definition of an ellipse.
"Elliptical" means they look like ellipses.
isn't it an arty word, like when you draw an ellipse-- so when you see/draw something with an ellipse you call it an elliptical drawing
Midpoint Ellipse Algorithm Midpoint ellipse algorithm is a method for drawing ellipses in computer graphics. This method is modified from Bresenham's algorithm. The advantage of this modified method is that only addition operations are required in the program loops. This leads to simple and fast implementation in all processors. Let us consider one quarter of an ellipse. The curve is divided into two regions. In region I, the slope on the curve is greater than -1 while in region II less than -1. dy/dx = -1 Region II Region I a b x y m = -1 Consider the general equation of an ellipse, b2x2 + a2y2 - a2b2 = 0 where a is the horizontal radius and b is the vertical radius, we can define an function f(x,y) by which the error due to a prediction coordinate (x,y) can be obtained. The appropriate pixels can be selected according to the error so that the required ellipse is formed. The error can be confined within half a pixel. Set f(x,y) = b2x2 + a2y2 - a2b2 In region I (dy/dx > -1), (xk, yk) Prediction (xk+1, yk-½) SE E Region I x is always incremented in each step, i.e. xk+1 = xk + 1. yk+1 = yk if E is selected, or yk+1 = yk - 1 if SE is selected. In order to make decision between S and SE, a prediction (xk+1, yk-½) is set at the middle between the two candidate pixels. A prediction function Pk can be defined as follows:
No. Both foci are always inside the ellipse, otherwise you don't have an ellipse.

As you were copying the question, did you notice the drawing alongside it ? Well, see, that sketch is actually part of the question; anybody who wants to try and answer it needs to see that drawing.
