Question 1137060: Find an equation of the ellipse that has center (1,1) a major axis of length of 10 , and endpoint of minor axis (0,1) Answer by ikleyn(52797) (Show Source):
The minor axis is horizontal, parallel to x-axis (!);
hence, the major axis is vertical, parallel to y-axis.
Major semi-axis is 5 units long; minor semi-axis is 1 unit long.
The ellipse is taller than long.
The equation has the form
+ = 1.
