Given:
Center is at the origin
and Major axis is along x – axis
So, Equation of ellipse is of the form
…(i)
Given that ellipse passing through the points
and
So, point
and
will satisfy the eq. (i)
Taking point
where x =
and y =
Putting the values in eq. (i), we get
…(ii)
Taking point
where x =
and y =
Putting the values in eq. (i), we get
…(iii)
Now, we have to solve the above two equations to find the value of a and b Multiply the eq. (iii) by 16, we get
…(iv)
Subtracting eq. (iv) from (ii), we get
Substituting the value of
in eq. (iii), we get
TThus,
Substituting the value of
in eq. (i), we get
