@westofer I never really took a lot of calculus in school. Later when I've done it for my personal stuff (mostly related to physics) I have never bothered making the c explicit.
Also my main maths tool of choice, Maxima, doesn't include it either.
When does it really matter?

@mur2501 @westofer right, but why do they do that if no one ever bothers in practice?
