Evaluate the riemann sum for (x) = x3 − 6x, for 0 ≤ x ≤ 3 with six subintervals, taking the sample points, xi, to be the right endpoint of each interval. give three decimal places in your answer. explain, using a graph of f(x), what the riemann sum in question #1 represents. express the given integral as the limit of a riemann sum but do not evaluate: the integral from 0 to 3 of the quantity x cubed minus 6 times x, dx. use the fundamental theorem to evaluate the integral from 0 to 3 of the quantity x cubed minus 6 times x, dx. (your answer must include the antiderivative.) use a graph of the function to explain the geometric meaning of the value of the integral. evaluate the riemann sum for (x) = x3 − 6x, for 0 ≤ x ≤ 3 with six subintervals, taking the sample points, xi, to be the right endpoint of each interval. give three decimal places in your answer. explain, using a graph of f(x), what the riemann sum in question #1 represents. express the given integral as the limit of a riemann sum but do not evaluate: the integral from 0 to 3 of the quantity x cubed minus 6 times x, dx. use the fundamental theorem to evaluate the integral from 0 to 3 of the quantity x cubed minus 6 times x, dx.
