Answer:
(a) General form of ellipse is.
[tex]\frac{(x-x_o)^2}{a^2} +\frac{(y-y_o)^2}{b^2} =1[/tex]
where a and b are major and minor axes both in x and y.
(b) at the origin, it is
[tex]\frac{x^2}{a^2} +\frac{y^2}{b^2} =1[/tex]
Explanation:
Origin is at (0,0) we put in these coordinate for [tex](x_o, y_o)[/tex].
