# What is the delta in mathematics?

Delta is a symbol used in mathematics and science that represents change. For example, delta y over delta x means the change in y over the change in x.

### What does the symbol pyramid mean?

That pyramid symbol (or better defined as a triangle as to not get confused with lower mathematics / geometry) simply means a change in something. The actual term is "delta" and it is also known as the derivative of y as seen here: (delta) y / (delta) x. (delta) y / (delta) x would be read as the change in y with respect to x.

### What is the definition of delta?

The answer depends on the context. Delta is a letter of the Greek alphabet and is shaped like a triangle. Mouths of rivers, which are often triangular in shape are, therefore, also called deltas. In mathematics, delta is often used to denote a change, particularly a small change. There is also the Dirac delta function which is an asymptotic spike function and is used in quantum physics.

### What is pure math?

Pure Mathematics is the branch of mathematics that deals only with mathematics and how it works - it is the HOW of mathematics. It is abstracted from the real world and provides the "tool box" of mathematics; it includes things like calculus. Applied mathematics is the branch of mathematics which applies the techniques of Pure Mathematics to the real world - it is the WHERE of mathematics; it includes things like mechanics. Pure Mathematics teaches…
