Solution: The integral ∫ 1 4 x 2 + 4 d x with n = 5 using midpoint rule. The midpoint rule formula is: ∫ a b f ( x) = Δ x ( f ( x 0 + x 1 2) + f ( x 1 + x 2 2) + f ( x 2 + x 3 2) +... + f ( x n – 2 + x n – 1 2) + f ( x n – 1 + x n 2)) Where Δx = b – a / n. We have a = 1, b = 4, n = 5. So, Δx = 4 – 1 / 5 = 0.6.
Midpoint rule for definite integrals: Enter a function f(x), use the a and b sliders to choose the limits of integration, and use the n slider to increase the number of subintervals.

Formula. The formula of the midpoint rule of the given function is: a ∫ b f (x) dx= Δx/2 [f (x 0 +x 1 )/2+ f (x 1 +x 2 )/2+…+ f (x n-2 +x n-1 )/2+f (x n-1 +x n )/2] where Δx= (b-a)/n. f (x) is the function whose midpoint is required. a and b are the lower limit and upper limit respectively. Δx is the length of the subinterval.

20 lut 2024 · This calculator employs the midpoint rule, a numerical method that divides the interval into smaller subintervals and calculates the area under the curve by using the midpoint of each subinterval. It provides an efficient and accurate way to estimate integrals without the need for complex analytical techniques.
