In this section we will introduce the notation of the limit. We will also take a conceptual look at limits and try to get a grasp on just what they are and what they can tell us.

In mathematics, a limit is the value that a function (or sequence) approaches as the argument (or index) approaches some value. [1] . Limits of functions are essential to calculus and mathematical analysis, and are used to define continuity, derivatives, and integrals.
Limits can be used even when we know the value when we get there! Nobody said they are only for difficult functions. We know perfectly well that 10/2 = 5, but limits can still be used (if we want!) Infinity is a very special idea. We know we can't reach it, but we can still try to work out the value of functions that have infinity in them.
limit, restrict, circumscribe, confine mean to set bounds for. limit implies setting a point or line (as in time, space, speed, or degree) beyond which something cannot or is not permitted to go.
So 'the limit of sin (x) as x→∞' is a well-defined concept; it's the real number that satisfies the ε-δ definition of that limit. It's just that no such real number exists, so we say the limit doesn't exist.
Use a table of values and graphs to estimate and/or evaluate limits and identify when limits do not exist. Evaluate and construct examples illustrating one-sided limits. Explain that a two-sided limit exists if and only if the left-hand and right-hand limits exist and are equal.
