Whether you want to program a calculator or just approximation an integral on paper, break out some numerical approximation tools like Simpson's Rule and the Trapezoid Rule.
Suppose \(T, L,\) and \(R\) are the approximation values using the Trapezium rule, left Riemann sum, and right Riemann sum, respectively, of the integral \(\displaystyle{\int_0^{1}(16-x^2)dx}\) using \(19\) intervals. Which of the following is the correct relationship between the three approximations?
