A linear functional is a mathematical function that maps a vector space into its scalar field.

Composite functions are used in mathematics to combine two or more functions into a single function.

Constant functions are functions that always return the same value.

Even functions are symmetric about the y-axis.

Symmetric functions are widely used in algebraic combinatorics.

Recursive functions are used in computer programming to solve complex problems.

I have been studying random functions for my research.

Scalar functions are used to perform calculations on individual values and return a single result.

Regular functions are essential for the proper functioning of the system.

The scattering functions of the particles were measured and analyzed.
