There are people here who know stuff about math, right? Could I ask someone to help me understand something I'm just not getting? I posted a question (https://math.stackexchange.com/questions/3349594/are-the-definite-and-indefinite-integrals-actually-two-different-things-where-i) on stackexchange but all that's resulted in is conversations in the comments going in circles.
@CoronaCoreanici @starkatt Ah I should have posted a follow-up, someone ended up posting a good answer on stackexchange! https://math.stackexchange.com/a/3349699/560186
Turns out the confusion was just in terminology--the distinction that was being made was between the integral and the antiderivative, but they were using "indefinite integral" to mean "antiderivative".
@CoronaCoreanici @starkatt if you want to, go right ahead!
