## FAQ's

### What is the Trapezoidal Rule in Calculus?

In calculus, the trapezoidal rule is an integration rule that is used to calculate area under a curve. It integrates the whole curve by dividing it into smaller trapezoids to calculate area. You can also use trapezium rule calculator. Mathematically, the trapezoidal rule is written as;

$∫_a^b f(x)dx≈T_n\;=\;\frac{∆x}{2} [f(x_o )+2f(x_1 )+2f(x_2 )+⋯+2f(x_{n-1} )+f(x_n)]{2}$

### When does Trapezoidal Rule Overestimate?

The trapezoidal rule systematically overstates the value of a function's definite integral over intervals where the function is concave up and systematically underestimates the value over intervals that are concave down. You can also estimate by using trapezoidal rule table calculator.

### How to use Integral to Find Area of Trapezoid?

You can simply integrate the function of trapezoid over the given interval to find area. The best value to find area of trapezoid is integration because it integrates any area under a curve on the particular interval. If you have integral values you can use online trapezoid rule integral calculator for quickly results.

### How to use Trapezoidal Rule to Estimate an Integral?

To estimate an integral by using trapezoidal rule, use the following steps.

- Find the length of intervals ∆x=(b-a)/n.
- Determine the function values on the values of x.
- Use above gathered information in the trapezoidal rule such that,

$ ∫_a^b f(x)dx ≈ T_n \;=\; \frac{∆x}{2} [f(x_o )+2f(x_1 )+2f(x_2 )+⋯+2f(x_{n-1} )+f(x_n)] {2}$

If you want to estimate the integral online you can use trapezoidal rule for double integral calculator.
