However, if we did make this guess we would be wrong. Consider any of the following function evaluations.

Calculus introduction to limits

Introduction and Basic Definitions The concept of a limit is fundamental to Calculus. In fact, Calculus without limits is like Romeo without Juliet. It is at the heart of so many Calculus concepts like the derivative, the integral, etc. So what is a limit?

Maybe the best example to illustrate limits is through average and instantaneous speeds: Let us assume you are traveling from point A to point B while passing through point C.

Then we know how to compute the average speed from A to B: Though we know how to compute the average speed this has no real physical meaning. Indeed, let us suppose that a policeman is standing at point C checking for speeders going through C.

Then the policeman does not care about the average speed. He only cares about the speed that you see on the speedometer, the one that the car actually has when crossing C. That one is real. How do we compute this "instantaneous speed"? That's not easy at all! Naturally one way to do this is to compute the average speed from C to points close to C.

In this case, the distance between these points and C is very small as well as the time taken to travel from them to C. Then we look at the ratio: Do these average speeds over small distances get close to a certain value? If so, that value should be called be the instantaneous speed at C.

In fact, this is exactly how the policeman's radar computes the driver's speed! Let us express this more mathematically. If s t is a function that determines the position of the moving object, and assume that at time t0, the moving object is at C.

Atwe are at a point close to C.Chapter 12 Limits and an Introduction to Calculus Section Introduction to Limits Objective: In this lesson you learned how to estimate limits and use properties and operations of limits.

The concept of limit of a function is the most important of all calculus. It is used to define derivation and integration, which are the main ideas of calculus. To make it simple, the limit of a function is what the function "approaches" when the input (the variable "x" in most cases) approaches a specific value.

Introduction to Calculus. Calculus is the study of change and motion, in the same way that geometry is the study of shape and algebra is the study of rules of operations and is the culmination of algebra, geometry, and trigonometry, which makes it the next step in .
