An isosceles triangle has one vertex at the origin, with its other two vertices above the origin and symmetrically located on the parabola y = 5 – 2x2. The vertices on the parabola are symmetric with respect to the y-axis. Use calculus to find the largest possible area of the triangle. *Hint: Be sure to use a sign chart with the first derivative or the second derivative test to demonstrate you have a maximum.
