This is my first course in Calculus as a Junior in college and it's already much differant then what I'm used to. I could use some help in understanding several theorems used to describe limits. The first states that the lim k = k as x--> aThe book describes it as being a constant function, so it's the same on either side of the limit The second states that the lim x = a as x-->a]. The book describes it as saying that if x approaches, so must f(x) but I don't understand that. If someone could explain or show me an example of these so I can understand what they're trying to say I'd really appreciate it.
