Find the equation of an ellipse with its...

Find the equation of an ellipse with its foci on y-axis, eccentricity `3/4` , centre at the origin and passing through (6,4).

Text Solution

Verified by Experts

we know that eccentricity of the ellipse is
`e=sqrt((a^2-b^2)/a^2)`
by putting ` e=3/4` and solving we get ` a^2=(7b^2)/16`
also by substituting the values `(6,4)` in the ellipse standard equation we get
...
