Try not to overthink this. As has been mentioned, an indefinite integral represents the whole class of integral solutions. It's like...

The indefinite integral is an equivalence class of antiderivatives. The integral ##\int_a^x f(t) dt## is a function of ##x##. Or, a...

I remembered a pretty high school problem from kinematics. But it seems it can help even undergraduates to develop their understanding...

For 1, this is part of the Fundamental Theorem of Calculus. For 2, if F(x) is an antiderivative of f(x), then so too will F(x) + C be...

I've always thought of indefinite integrals as ones with unspecified integration limits. Wikipedia gets into it in more detail...
