Definition (Sequence): A set of numbers arranged in a definite order according to some definite rule (or rules) is called a sequence. Each number of the set is called a term of the sequence. A sequence is called finite or infinite according as the number of terms in it is finite or infinite. The different […]
Definition: A formula is a relation between certain quantities. For example, if side of a square then its perimeter can be expressed by the following formula which we already know, i.e., . This formula shows the relationship between the side of a square and the perimeter of a square. If we know the values of […]

This lesson covers the basic concept of limit to a variable and a function and what we understand by x tending to infinity. We will also see some Important limits.
What is a set? A set is a collection of well-defined and distinct objects. Every object of the collection forming a set is called a member or element of the set. When an object is a member of a set we say that the object belongs to the set. Any collection of objects is not […]

Remainder Theorem: If a polynomial f(x) is divided by x-r, the remainder is equal to the value of the polynomial where r is substituted for x. Divide the polynomial by x-r until the remainder, which may be zero is independent of x. Denote the quotient by Q(x) and the remainder by R. Then according to the meaning of the division, f(x) = (x-r) Q(x) + R.
