Angle Brackets Math
The angled brackets represent an inner product.
Angle brackets math. The best known one is the scalar product or the dot product. Generally such bracketing denotes some form of grouping. An angle bracket is the combination of a bra and ket bra ket bracket which represents the inner product of two functions or vectors or 1 forms f g intf x g x dx in a function space or v w v w in a vector space. The angle bracket or which is also called an inequality sign for its use in mathematics is a kind of sideways caret that can be used to include tags or pieces of code.
In evaluating an expression containing a bracketed sub expression the operators in the sub expression take precedence over those surrounding it. Historically other notations such as t. Additionally there are several uses and meanings for the various brackets. Angle brackets also called chevrons are not generally used as grouping symbols bare delimiters in mathematics.
But normally they are only used for very narrow specialized purposes.
