About Trapezoidal Rule Calculator

A trapezoidal rule calculator for numerical integration. Approximates ∫f(x)dx using trapezoids: T = (h/2)[f(a)+2f(x₁)+...+2f(xₙ₋₁)+f(b)]. Shows error estimate, compares with Simpson's rule, and allows adjustable subdivisions. All calculations are client-side. Essential for numerical analysis, physics, and engineering.
