If you did LRAM and RRAM with uneven intervals, that actually should work for mathematical correctness. Whether you'd get credit for it when it explicitly asks for the trapezoidal rule, I don't know.

LRAM = L(0) + 2L(1) + L(3)
RRAM = L(1) + 2L(3) + L(4)
(LRAM + RRAM)/2 = [L(0) + 3L(1) + 3L(3) + L(4)]/2

Trapezoidal Rule:
[L(0) + L(1)]/2 + 2*[L(1) + L(3)]/2 + [L(3) + L(4)]/2 =
[L(0) + 3L(1) + 3L(3) + L(4)]/2

So... maybe?

nns91, I see 3 points for that question, and I'm guessing you would get 2 out of 3.
