Question: what is the difference between integral and antiderivative?
Answer: In general, “Integral” is a function associate with the original function, which is defined by a limiting process. ... The antiderivative of x² is F(x) = ⅓ x³. The indefinite integral is ∫ x² dx = F(x) = ⅓ x³ + C, which is almost the antiderivative except c. (where “C” is a constant number.)
