limits functions Limits An Introduction 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
Use the limit laws to evaluate the limit of a polynomial or rational function Evaluate the limit of a function by factoring or by using conjugates Evaluate the limit of a function by using the squeeze theorem In the previous section we evaluated limits by looking at graphs or by constructing a table of values Evaluating the limit of a function at a point or evaluating the limit of a function from the right and left at a point helps us to characterize the behavior of a function around a given value As we shall see we can also describe the behavior of functions that do not have finite limits

The limit of a function at a point a a in its domain if it exists is the value that the function approaches as its argument approaches a a The concept of a limit is the fundamental concept of calculus and analysis 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
Limits of combined functions products and quotients Limits of composite functions Limits by direct substitution Direct substitution with limits that don t exist Limits of trigonometric functions Limits of piecewise functions Limits and continuity Quiz 2 Limits by factoring 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

2 3 6 Evaluate the limit of a function by using the squeeze theorem In the previous section we evaluated limits by looking at graphs or by constructing a table of values In this section we establish laws for calculating limits and learn how to apply these laws Not all functions have limits at all points and we discuss what this means and how we can tell if a function does or does not have a limit at a particular value The last section of this chapter presents the more precise definition of a limit and shows how to prove whether a
