In numerical analysis, compound trapezoid formula is often used to evaluate the approximate value of ∫ b af(x) d x which meets specified precision. Expecially, when primitive function can't be found, the advantage lay definitely with it. The article introduces how to derive the summation formula of ex n of sequence of number using the compound trapezoid formula.
