In mathematics, brackets of various typographical forms, such as parentheses ( ), square brackets [ ], braces { } and angle brackets ⟨ ⟩, are frequently used in mathematical notation. Generally, such bracketing denotes … See more

A variety of different symbols are used to represent angle brackets. In e-mail and other ASCII text, it is common to use the less-than (<) and … See more

The arguments to a function are frequently surrounded by brackets: $${\displaystyle f(x)}$$. With some standard function when there is little chance … See more

An explicitly given matrix is commonly written between large round or square brackets:
$${\displaystyle {\begin{pmatrix}1&-1\\2&3\end{pmatrix}}\quad \quad {\begin{bmatrix}c&d\end{bmatrix}}}$$ See more

In elementary algebra, parentheses ( ) are used to specify the order of operations. Terms inside the bracket are evaluated first; hence 2×(3 + 4) is 14, 20 ÷ (5(1 + 1)) is 2 and (2×3) + 4 is … See more

In the Cartesian coordinate system, brackets are used to specify the coordinates of a point. For example, (2,3) denotes the point with x-coordinate 2 and y-coordinate 3.
The inner product of two vectors is commonly written as See more

The notation
$${\displaystyle f^{(n)}(x)}$$
stands for the n-th derivative of function f, applied to argument x. So, for example, if $${\displaystyle f(x)=\exp(\lambda x)}$$, then $${\displaystyle f^{(n)}(x)=\lambda ^{n}\exp(\lambda x)}$$ See more
