The first derivative is found using the quotient rule. f'(x) = [x(x+8)] / [(x+4)^2] The second derivative is found using the product rule. f''(x) = [32] / [(x+4)^3] f''(5) = [32] / {[(5)+4]^3}

The approximation to a definite integral using n=10 is 2.346; the exact value is 4.0. If the approximation was found using each of the following rules, use the same rule to estimate the integral with n=30. A) Left Rule B) Trapezoid Rule The section deals with approximation ...
