Area Under Curve Calculator
Approximate the area under a curve using the trapezoidal rule. Enter x,y data points and get the numerical integral. Supports comma, space, or tab-separated values.
How to Use Area Under Curve Calculator
The Area Under Curve Calculator approximates the definite integral of a function using the trapezoidal rule. Enter your data as x,y pairs (one per line) and the tool calculates the area by summing trapezoids between consecutive points. Points are automatically sorted by x-value. Useful for physics (work, displacement), statistics (probability), engineering (signal energy), and any situation where you have discrete data points and need the area. Supports comma, space, or tab-separated values.
