 Emeritus Sci Advisor PF Gold P: 16,099 By "primitive" do you mean that if $f(x) = \int g(x) \, dx$ then $f(x)$ is a primitive of $g(x)$? (The usual English word for this is that $f(x)$ is an antiderivative or an integral of $g(x)$) I'm not entirely sure what you're trying to ask... though it is false that any function is an antiderivative of another function.
