Formula
∫ f(x) dx = F(x) + C | Definite: ∫[a,b] f(x) dx = F(b) - F(a)
Worked Example

bounds0 to 3
Result: 9The definite integral of x² from 0 to 3 equals 9, representing the signed area under the curve over that interval.
Frequently Asked Questions
What is the difference between definite and indefinite integrals?
Indefinite integrals return a family of antiderivatives plus C, while definite integrals return one numeric value over specified bounds.
