Polynomial Integral

Enter a polynomial in x. The calculator finds the antiderivative with the reverse power rule ∫ c·xⁿ dx = c/(n+1)·xⁿ⁺¹ + C. Supply both limits a and b to also evaluate the definite integral as F(b) − F(a).

Frequently asked questions

How do I get a definite integral?

Fill in both the lower limit a and the upper limit b. Leave them blank for the indefinite integral.

Why is there a + C?

Indefinite integrals are determined only up to an arbitrary constant, written + C.

Is the result exact?

Yes. Polynomial integration is symbolic and exact, including the definite-integral evaluation.
