Great lecture, but with a this critical error: The lecture INCORRECTLY states that, "parabolas whole axis of symmetry is horizontal have equations of the form y=a(x-k)^2 + h, but in fact you need to switch the x and the y in the equation to make this a true statement: x = a(y-k)^2 + h would produce a horizontal parabola.
