Free Trapezoidal Approximation calculator - approximate the area of a curve using trapezoidal approximation step-by-step
An online trapezoidal rule calculator helps you to estimate the area under the graph of the given function using the trapezoidal rule. The free trapezoid area calculator approximates the integral in multiple subintervals with step-wise calculations.
Trapezoidal 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.
The following is the Trapezoidal Rule formula used by the trapezoid calculator for calculating the definite integral of a function f(x): $$ \int_a^b f(x) \, dx \, ≈ \, T_n \, = \, \frac{Δx}{2} [f(x_0) \, + \, 2f(x_1) \, + \, 2f(x_2) \, + \, ... \, + \, 2f(x_{n-1}) \, + \, f(x_n)]$$
