Free Trapezoidal Approximation calculator - approximate the area of a curve using trapezoidal approximation step-by-step
The Trapezoidal Rule Calculator efficiently dissects the area under the curve, computes the trapezoids, and delivers a precise approximation of the definite integral. Trapezoidal Rule Formula. The Trapezoidal Rule formula for approximating the definite integral of a function \( f(x) \) over the interval \([a, b]\) is:
The trapezoid calculator is a valuable computational tool designed to simplify the estimation of definite integrals by applying the trapezoidal rule—a numerical technique in calculus. This user-friendly calculator enables individuals to approximate the area under a curve by dividing the interval into smaller trapezoids and summing their areas.
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 area of a trapezoid is given by A = 1 2 ( B 1 + B 2 ) ⋅ h where B 1 and B 2 are the lengths of the vertical bases and h is the height (which is horizontal in this case).
