Problema Solution
focus at (-square root of 13,0), vertex at (o,2).solve for the equation of an ellipse.
Answer provided by our tutors
We assume the equation of an ellipse is x^2/(a^2) + y^2/(b^2) = 1
c = square root of 13, so c^2 = 13
vertex at (o,2), so b^2 = 2^2 = 4
So a^2 = b^2 + c^2 = 4 + 13 = 17
So
the equation of an ellipse is x^2/17 + y^2/4 = 1
