• ## Standard Form of a Number: Definition, Representation, and Examples

Numbers are a basic element in our daily life. Numbers may be challenging, especially when there are several digits involved. To make such numbers easier to understand, mathematicians use the standard form method. The standard form of a number helps to write extremely large or extremely small numbers easier.

• ## Standard deviation: Definition, Formulas, Uses, and Examples

In statistics, a standard deviation is a measure of the variability of a set of data points. It is also used to measure the spread of data from the average value. In data analysis and interpretation, the study of standard deviation is very essential. The term standard deviation is very helpful to identify unusual data…

• ## Limit of a function: Definition, Types, Properties, and Calculations

In 1861, first-time mathematician Karl Weierstrass defined a limit by using the epsilon-delta. To represent the limit of the function, he used the symbol lim. In 1908, Hardy was the first to use the arrow sign below the limit in the book “A Course of Pure Mathematics”. Derivation, integration, and continuity is some important application…
