Help!

I have drawn a parabolic shape using the formula y = X^2

The parabola is composed of spheres scaled into ellipses with the longside
in the y direction

I have been trying to rotate each ellipse so the the length is pointing in
the direction of the parabola

I need to calculate the gradient at each point. I'm no mathmatician so
Please help
