    Ellipse Optimization

    I am given the equation 2x^2 + 0.2y^2 = 1

    and I need to find the point whose coordinate have the largest sum (The sum of the x and y values)

    I'm not really sure where to start. any ideas?

    solve for y in terms of x

    sum, S = x + (y in terms of x)

    find dS/dx and maximize S
