How will u find out that if the point is outside, on or inside the ellipse ?

Hence show that the triangle whose verities are (1,2), (3,-11) and (-2,1) lies wholly inside the ellipse

Look at the standard form equation of the ellipse:

if the constant a>b it represents the length of the major axis, and if a<b it represents the minor axis. The same thing applies to "b".

You can now sketch the ellipse. But you can also check this without drawing a graph, if you have studied the quadratic forms. - Jan 7th 2010, 09:16 PMShanks
substitute with , If the value is less than 1, then inside; equal to 1, lie on the curve; is greater than 1, outside.
