[alogo] Maximal Ellipse inscribed in a square

The maximal Ellipse inscribed in a square is the incircle of the square.

This follows immediately from the relation between the square side x and the axes of the ellipse inscribed in the square. They satisfy the relation (prove it) a² + b² = x²/2. Under this condition, for constant x, the area of the ellipse E(a,b) = pi*a*b, becomes a maximum when a = b = x/2.
