Subscript Notation Math Definition

Subscripts have many scientific applications including mathematics computer science and chemistry.

Subscript notation math definition. The number 1 here. In programming a number of notations are used to denote hexadecimal numbers usually involving a prefix or suffix. F n f n 1 f n 2. The small n is a subscript.

Introduction in this appendix we outline the notation that we use in this book and then. A small letter or number placed slightly lower than the normal text. In mathematics a subscript is typically used to specify the base. A number value in a sequence is called a term of the sequence.

Notation a matrix is usually shown by a capital letter such as a or b each entry or element is shown by a lower case letter with a subscript of row column. Sequences and series are most useful when there is a formula for their terms. Once a value of y is chosen say a then f x y determines a function f a which traces a curve x 2 ax a 2 on the plane. Below is an example of a math function that uses subscripts to define the fibonacci sequence.

Make sure you understand the difference between notation with and without braces. For instance if the formula for the terms a n of a sequence is defined as a n 2n 3 then you can find the value of any term by plugging the value of n into the formula. A subscript is a character or string that is smaller than the preceding text and sits at or below the baseline. The i in zi is a subscript.

The simplest notation for defining a sequence is a variable with the subscript n surrounded by braces. You can reference a specific term in the sequence by using the subscript. In this section the subscript notation f y denotes a function contingent on a fixed value of y and not a partial derivative. For example the decimal value 31 181 would be expressed in hexadecimal as 79cd 16.

Subscripts are small italic letters or numbers below and to the right of normal mathematical symbols. For instance a 8 2 8 3 16 3 19 in words a n 2n 3 can be read as the n th term is given by two enn plus three. Notation matrices and matrix mathematics a 1. Mathematics is concerned with numbers data quantity structure space models and change.

A sequence is a list of numbers values exhibiting a defined pattern. X m pronounced x sub m or just x m often used when we have a list of values.
