Answer with explanation:
Equation of ellipse in two forms
[tex]\frac{x^2}{a^2}+\frac{y^2}{b^2}=1[/tex]
So, there are two cases.
1. When , a > b
Major Axis = X axis
Minor Axis =Y axis
Focus , lies on the Major Axis that is on X axis.
2. When, a < b
Major Axis = Y axis
Minor Axis = X axis
Focus lies on the Major axis, which is Y axis.
So, In both the cases ,the Focus lies on Major Axis.
