After studying this chapter, you will be able to understand:

Know the concept of limit and continuity

Understand the theorems (statements) and formula of limit and definition of continuity

Know how to solve the problems related to limit and continuity with the help of given illustrations

Limit and Continuity is a branch of calculus. Intuitively we call quantity *y* a function of another quantity *x* if there is a rule by which a unique value of *y* is associated with a corresponding value of *x.*

When value of *x* is very close to certain value *a,* then functional value f(x) goes on becoming l. Then symbolically we can say that

*Note:* Meaning of x →*a* (x ...
