In mathematics, delta is a symbol representing a change in something. It is mostcommonly used in calculusto indicate the slope of a line tangent to a curve at a given point. Delta can also mean the difference between two values or the derivative of a function at a certain point. Because ...
Lower-case delta (δ) also has more specific functions in advanced mathematics. The Kronecker delta, for example, represents a relationship between two variables, which is 1 if the two variables are equal, and 0 if they are not. Most students of mathematics won't have to worry about these ...

A basis ei is orthogonal if all its members are orthogonal to one another, and orthonormal if, in addition, all its members are of unit norm. Thus we may write 〈ei,ej〉=δij (ei orthonormal). The Kronecker symbol δij has the value 1 if i and j are equal, and has the ...
