Midpoint Rule with EXCEL. The problem can be solved with the following worksheet (the formulas are shown below): The initial x is a+dx/2, where a is the lower limit of integration. Compare this midpoint rule approximation with the actual value of .286450284649, obtained from a graphing calculator.
Figure 4 – Midpoint rule for integration On the left side of the figure, we show how to manually calculate the definite integral ∫ f ( x ) dx from x = 1 to x = 2 by using the midpoint rule with 10 subintervals to obtain the value .149889.
The Midpoint Rule is a numerical method used to approximate the value of a definite integral. It provides a way to estimate the area under a curve, which is particularly useful when the integral cannot be calculated directly.

Simpsons rule is a numerical method in calculus. It approximates the integral of a function between two limits of ‘a’ and ‘b’. It helps find the area under a parabola but above the x axis. SIMPSON’S RULE FORMULA. THE INTEGRAL WE ARE EVALUATING. DECIDING X VALUES USING. N.
Simpson's Rule uses a polynomial to approximate the behavior of the function between points and better approximate its integral. The approximating polynomial has three coefficients (three unknowns) and requires three function evaluations.
