Find the equation of
the ellipse with ecentricity
(1/2) and the focus (2,1)
Does the line x=3 touches
ellipse.if so at what
point?if line x=5 is the
line of direction.
The line y=mx+c touches
ellipse (x^2 /a^2 )+(y^2 /b^2 )=1
prove that the foot of
perpendicular from
focus into this line lie on
auxillary circle
x^2 +y^2 =a^2

he observes it in a direction N 67° E. How far is the school from the road.
