Math Problem Statement
Given the integral of (cos(x))/x dx from 1 to 6; Part a) Use the trapezoidal rule with six subintervals to estimate the value of the definite integral. (don't round the answer) Part b) Give an appropriate upper bound for the absolute error that results from this approximation. (don't round the answer)

Formulas
Trapezoidal rule: ∫_a^b f(x) dx ≈ (h/2) * [f(x_0) + 2 * Σ f(x_i) + f(x_n)], where h = (b - a)/n
Error bound for trapezoidal rule: |E_T| ≤ ((b - a)^3 / 12n^2) * max |f''(x)|
