Difference between sequence and series?

Posted by Sindhu George 8 years, 2 months ago

CBSE > Class 11 > Mathematics

1 answers

Pooja Choudhary 8 years, 2 months ago

The list of numbers written in a definite order is called a sequence. The sum of terms of an infinite sequence is called an infinite series. A sequence can be defined as a function whose domain is the set of Natural numbers. Therefore sequence is an ordered list of numbers and series is the sum of a list of numbers. Example of a sequence: 2, 4, 6, 8, 10 … Now if we add them up: 2+4+8+10+ … This is a series.

Permutation	Combination
The different ways of arranging a set of objects into a sequential order are termed as Permutation.	One of the several ways of choosing items from a large set of objects, without considering an order is termed as Combination.
The order is very relevant.	The order is quite irrelevant.
It denotes the arrangement of objects.	It does not denote the arrangement of objects.
Multiple permutations can be derived from a single combination.	From a single permutation, only a single combination can be derived.
They can simply be defined as ordered elements.	They can simply be defined as unordered sets.

Amar Kumar 8 years, 2 months ago

A translation of axes in two dimensions is a mapping from an xy-Cartesian coordinate system to an x'y'-Cartesian coordinate system. In this system the x' axis is parallel to the x axis and k units away, and the y' axis is parallel to the y axis and h units away.

The shifting of the reference axes without turning so that each axis remains parallel to its original position.
