Approaching ... Sometimes we can't work something out directly ... but we can see what it should be as we get closer and closer! Example: (x2 − 1) (x − 1) Let's work it out for x=1: (12 − 1) (1 − 1) = (1 − 1) (1 − 1) = 0 0. Now 0/0 is a difficulty!
Finding the Limit of a Sum, a Difference, and a Product. Graphing a function or exploring a table of values to determine a limit can be cumbersome and time-consuming. When possible, it is more efficient to use the properties of limits, which is a collection of theorems for finding limits.
HOW TO: Given a function \(f(x)\), use a graph to find the limits and a function value as \(x\) approaches \(a.\) Examine the graph to determine whether a left-hand limit exists. Examine the graph to determine whether a right-hand limit exists.

21 Δεκ 2020 · We begin our study of limits by considering examples that demonstrate key concepts that will be explained as we progress. Consider the function \(y = \frac{\sin x}{x}\). When \(x\) is near the value 1, what value (if any) is \(y\) near?
