Chapter 5. Numerical Integration

quadratic graph. Then we also need a formula for the ‘area under a quadratic graph’ (or the integral of it) analogous to the formula h 1 2 y 0 + 1 2 y 1 we used for the area of a trapezoid. 5.15 Lemma. If we have 3 points in the plane with different x-coordinates, then there is exactly one quadratic graph passing through them. Proof.
