Frequently Asked Questions
The trapezoidal rule is a numerical integration method that approximates the definite integral of a function by dividing the area under the curve into trapezoids and summing their areas.
Use x as the variable. Supported operators: +, -, *, /, ^ for power, and functions like sin, cos, tan, log, sqrt, pi, e. Example: x^2 + sin(x).
n is the number of subintervals (trapezoids). A larger n generally gives a more accurate approximation. Must be a positive integer.
