But what is the antiderivative of x to the n, and we could say the antiderivative with respect to x if we want to. And another way of calling this is the indefinite integral. Indefinite integral. Well we know, this is saying x to the n is the derivative of what? Well we just figured out, it's the derivative of this thing. And we've written it in very general terms. We're actually encapsulating multiple constants here.
