Question : Put the equation 4x^2 + 9y^2 = 36 in the standard form and sketch it. Indicate its center, vertex and foci

Solution :

I am getting a ellipse equation $\displaystyle \frac{x^2}{4} + \frac{y^2}{4} = 1$

and the e = 0

since the value of b and a are both the same i dont know how to plt the graph which one should i take as the major and minor axis
