How to Use the Integration Calculator
This calculator computes the definite integral of a polynomial function between two limits.
- Enter coefficients as comma-separated numbers (e.g.,
1,0,-2for x² − 2). The first number is the coefficient of x⁰ (constant), the second for x¹, the third for x², and so on. - Set the lower limit (a) and upper limit (b) in the number fields. Ensure b > a.
- Click Calculate Integral. The result appears below with a step-by-step breakdown showing the antiderivative, F(b), F(a), and the final value.
Note: All numbers are treated as real numbers. Use decimal points if needed (e.g., 0.5). The result is rounded to 4 decimal places.

Frequently Asked Questions
This calculator integrates polynomial functions. Enter coefficients separated by commas, starting from the highest degree term.
For example, for x^2 - 2, enter '1,0,-2' (coefficient for x^2, x, constant).
Check that all inputs are valid numbers, limits are numeric, and upper limit is greater than lower limit.
