Question 1137076: Find an equation of the ellipse that has center (5,-1)
, a major axis of length 4
, and endpoint of minor axis (6,-1)
. Answer by ikleyn(52797) (Show Source):
Minor axis is horizontal; minor semi-axis has the length 6-5 = 1 unit.
Major axis is vertical; major semi-axis has the length 4/2 = 2.
The ellipse is taller than wide.
The equation is
+ = 1, or, equivalently
+ = 1. ANSWER
