LIMIT
OVERVIEW
The concept of a limit is a central idea that distingushes
calculus from algebra and trigoniometry. It is fundamental
to finding the tangent to a curve or the velocity of an
object may be the car,plane,…
LEARNING OUTCOMES
In this presentation We use limits to describe the way a function f
varies. Some functions vary continuously; small changes in x produces
only small changes in f(x). Other functions can have values that jump
or vary erractically. The notion of limit gives a precise way to
distinguish between these behaviors. The geometric application of
using limits to define the tangent to a curve leads at once to the
important concept of derivative of a function.
CONCEPT OF LIMIT
THE LIMIT VALUE DOESN’T DEPEND ON HOW THE FUNCTION IS DEFINED AT A POINT
TWO SIDED LIMITS
TWO SIDED LIMITS• Right hand limit:
• Left hand limit:
• It the above two sided limits exists and they are equal then we say that
The limit: exists.
