The midpoint formula is a formula used to find the halfway point between two coordinates on a graph. Given a line segment with endpoints A and B, the midpoint is the point located exactly between A and B, meaning that it is the same distance from A and B, as in the figure below. The midpoint formula can be used when two points on a graph in the ...The rule is an extension of the trapezoidal rule, but it achieves a higher degree of accuracy by using quadratic polynomial approximations. Simpson's Rule is a way to find a good estimate for integrals. Instead of using straight lines like other methods, it uses curved lines called quadratic polynomials. These curves give us more accurate results.The rule is an extension of the trapezoidal rule, but it achieves a higher degree of accuracy by using quadratic polynomial approximations.

A problem asks to integrate the function f(x) = x 1+x4 f ( x) = x 1 + x 4 on [−1, 2] [ − 1, 2] using the Midpoint rule and the Trapezoidal rule, which I did in MATLAB. Then it asks to determine the value of this integral exactly up to 10 decimal places, after which it asks to do a log-log plot of the ... (And inversely, if the function is concave up, the Trapezoidal Rule will consistently overestimate the area.) With the Midpoint Rule, each rectangle will sometimes overestimate and sometimes underestimate the function (unless the function has a local minimum/maximum at the midpoint), and so the errors partially cancel out. 4. Midpoint Rule. The midpoint rule uses the midpoint of the rectangles for the estimate. A midpoint rule is a much better estimate of the area under the curve than either a left- or right- sum. As a rule of thumb, midpoint sums are twice as good than trapezoid estimates.Question: Use the Trapezoidal Rule, the Midpoint Rule, and Simpson's Rule to approximate the given integral with the specified value of n.
