It’s a mathematical concept meant to represent a really large value that can’t actually be reached. In terms of solutions of limits, it means that the equation you are taking the limit of will go in that direction forever. For example: You have a vertical asymptote at the y-axis (which is x = 0), which means ...

WebSome teachers will let you get away with writing lim f(0)=infinity, but others will require you to say that because the function tends towards infinity, the limit does not exist. *Infinity is not a number, but is instead a sort of amorphus value.

For instance, in order to show the non existence of lim x → 0 sin 1 x the easiest way is to show that the limit should be in the interval [ − 1, 1], but that sin 1 x assumes every value in [ − 1, 1] in each punctured neighborhood of 0, so it is far from every possible limit.

Let’s first take a closer look at how the function f(x) = (x2 − 4) / (x − 2) behaves around x = 2 in Figure 2.2.1. As the values of x approach 2 from either side of 2, the values of y = f(x) approach 4. Mathematically, we say that the limit of f(x) as x approaches 2 is 4.

WebJul 12, 2024 · Because the value of f does not approach a single number as x gets arbitrarily close to 1 from both sides, we know that f does not have a limit at a = 1. Since f does approach a single value on each side of a = 1, we can introduce the notion of left and right (or one-sided) limits.
