Question: is antiderivative and indefinite integral the same thing?
Answer: Indefinite integral means integrating a function without any limit but in definite integral there are upper and lower limits, in the other words we called that the interval of integration. The antiderivative of x² is F(x) = ⅓ x³. ... Deeply thinking an antiderivative of f(x) is just any function whose derivative is f(x).
