A code might look like this: import … WebbThe simplest method for approximating integrals is by summing the area of rectangles that are defined for each subinterval. The width of the rectangle is x i + 1 − x i = h, and the height is defined by a function value f ( x) for some x in the subinterval.
Webb4 maj 2024 · Usually, if both the limits were numeric I would get away with just applying simps from scipy.integrate twice, but here I have no idea how to proceed. python scipy Webb∫xi + 1 xi f(x)dx = hf(yi) + O(h3). Now if we substitute f(yi) with the expression derived explicitly in terms of f(xi) and f(xi + 1), we get ∫xi + 1 xi f(x)dx = h(f(xi + 1) + f(xi) 2 + O(h2)) + O(h3), which is equivalent to h(f(xi + 1) + f(xi) 2) + hO(h2) + O(h3) and therefore, ∫xi + 1 xi f(x)dx = h(f(xi + 1) + f(xi) 2) + O(h3).
