The graph of an ellipse is x^2-xy+y^2 = 3 is shown. What are the dimensions and the location of the box containing the ellipse.
note: the sides of the box are vertical and horizontal and also are tangent to the ellipse.
I NEED HELP. I went about to find the derivative first but I honestly have no idea on where to go from here on.. please help
well since the ellipse is tilted and therefore not symetrically to the x and y axis, the points i found are not the vertices of the box and i think when i drew it out, the points i got were actually tangent to the box. how do i go about finding the actual vertices.
