3.
If d is the distance between equidistant odd ordinates, the Simpson's rule for the areas, is
[h1 + hn + 2(h3 + h5 + ... + hn - 2) + 4(h2 + h4 + ... + hn - 1)]
[h1 + hn + 2(h3 + h5 + ... + hn - 2) + 4(h2 + h4 + ... + hn - 1)]
[h1 + hn x 2(h2 + h4 + ... + hn - 1) + 4(h3 + h5 + ... + hn - 2)][h1 + hn + 2(h3 + h5 + ... + hn - 2) + 4(h2 + h4 + ... + hn - 1)]none of these.
