multinomial, polynomial
a mathematical function that is the sum of a number of terms
expansion
a function expressed as a sum or product of terms
inverse function
a function obtained by expressing the dependent variable of one function as the independent variable of another; f and g are inverse functions if f(x)=y and g(y)=x
Kronecker delta
a function of two variables i and j that equals 1 when i=j and equals 0 otherwise
metric, metric function
a function of a topological space that gives, for any two points in the space, a value equal to the distance between them
transformation
(mathematics) a function that changes the position or direction of the axes of a coordinate system
isometry
a one-to-one mapping of one metric space into another metric space that preserves the distances between each pair of points
operator
(mathematics) a symbol or function representing a mathematical operation
circular function, trigonometric function
function of an angle expressed as a ratio of the length of the sides of right-angled triangle containing the angle
threshold function
a function that takes the value 1 if a specified function of the arguments exceeds a given threshold and 0 otherwise

reflection
(mathematics) a transformation in which the direction of one axis is reversed
rotation
