Numerical Integration
Use the error formulas to find bounds for the error in approximating the integral using (a) the Trapezoidal Rule and (b) Simpson's Rule. (Let $n=4 .)$ $$ \int_{0}^{1} \frac{1}{x+1} d x $$
If the definite integral $\int_{1}^{3}\left(x^{2}+1\right)$ is approximated by using the Trapezoid Rule with $n=4,$ the error is (A) 0 (B) $\frac{7}{3}$ (C) $\frac{1}{12}$ (D) $\frac{65}{6}$
