Imagine the curve as a series of connected line segments forming trapezoids, and the rule calculates the sum of these trapezoidal areas. The key idea is to divide the interval into smaller steps, evaluate the function at the endpoints of each step, and use the trapezoidal formula to find the area of each trapezoid. The trapezoidal rule offers a practical and straightforward approach to understanding and approximating integrals, making it a valuable tool in calculus.

Let a continuous function f(x) on the given bounded interval [a, b]. At this point, divide the bounded intervals [a, b] into n equal subintervals with each distance across Δx=b-a/n, in which a = x0 < x1< x2 < x3 <..<. xn = b.

The following is the Trapezoidal Rule formula used by the trapezoid calculator for calculating the definite integral of a function f(x):

$$ \int_a^b f(x) \, dx \, ≈ \, T_n \, = \, \frac{Δx}{2} [f(x_0) \, + \, 2f(x_1) \, + \, 2f(x_2) \, + \, ... \, + \, 2f(x_{n-1}) \, + \, f(x_n)]$$

Where xi = a + iΔx

If n→∞, then the right-hand side of this expression approaches the definite integral. This formula encapsulates the essence of the trapezoidal rule, providing a clear and practical method for approximating definite integrals and showcasing the simplicity that makes it an invaluable tool in calculus problem-solving.

**Example:**

Calculate the area under the curve with the help of the Trapezoidal Rule Formula through the following points:

x |
0 | 0.5 | 1 | 1.5 |

f(x) |
5 | 6 | 9 | 11 |

**Solution:**

Given data;

$$ x_0 = 5, \; x_1 = 6, \; x_2 = 9, \; x_3 \, = \, 11 $$ $$ 0.5 \, - \, 0 \, = \, 0.5 $$ $$ \text{Area of the Trapezoid Formula:} = $$ $$ \frac{Δx}{2} [x_0 \, + \, x_n \, + \, 2 \, (x_1+x_2+x_3…. x_{n-1})] $$ $$ = \, \frac{0.5}{2} [5 \, + \, 11 \, + \, 2 (6 \, + \, 9)] $$ $$ \text{Then the result is;} $$ $$ \text{The area under the curve = 11.2 square units.} $$

The trapezoidal rule in calculus simplifies the process of finding definite integrals by breaking down the area under a curve into smaller trapezoids. Instead of complex shapes, it connects points on the curve with straight lines to form these trapezoids. The rule then calculates the sum of their areas, providing a practical and accessible way to approximate the total integral.

To find the area of a trapezoid using integrals, consider the trapezoid as a geometric shape with one pair of parallel sides. If 'a' and 'b' are the lengths of the two parallel sides and 'h' is the height, you can set up an integral using the formula 1/2 * (a + b) * h. The integral ∫[a, b] (1/2 * (a + b)) dh represents the area under the curve of the trapezoid. By evaluating this integral, you obtain the area of the trapezoid, offering a mathematical method to calculate its geometric space.

Use the trapezoidal rule for integral approximation. Start by dividing the interval into smaller subintervals. Calculate the function values at the endpoints of these subintervals. Then, apply the trapezoidal rule formula: h/2 * (f(x₀) + 2f(x₁) + 2f(x₂) + ... + 2f(xₙ-1) + f(xₙ)), where 'h' is the width of each subinterval and 'n' is the number of subintervals. Summing up these values provides an estimate of the integral, making the trapezoidal rule a practical and accessible numerical technique in calculus.
