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.

The psi functions are used to describe the wave functions of quantum systems.

Propositional functions are important in mathematical logic.
