Derivative In calculus the derivative is a measure of how a function changes as its input changes. Loosely speaking, a derivative can be thought of as how much one quantity is changing in response to changes in some other quantity; for example, the derivative of the position of a vehicle with respect to time is the vehicle's instantaneous velocity, in calculus, is a measurement of how a function changes when the values of its inputs change.
Derivative may also refer to:
- Derivative (finance) A derivative, in non-financial-expert terms, is an agreement or contract that is not based on a real, or true, exchange, i.e.: There is nothing tangible like money, or a product, that is being exchanged. For example, a person goes to the grocery store, exchanges a currency for a commodity (say, an apple). The exchange is complete, both parties, a contract whose value is derived from that of other quantities
- Derivative (chemistry) In chemistry, a derivative is a compound that is derived from a similar compound or a compound that can be imagined to arise from another compound, if one atom is replaced with another atom or group of atoms. The latter definition is common in organic chemistry. In biochemistry, the word is used about compounds that at least theoretically can be, a type of compound which is a product of the process of derivatization
- Derivative Inc., a spin-off of Side Effects Software, creators of Houdini (software)
- Derivative suit or derivative action, a type of lawsuit filed by minority shareholders
- Derivative work In the United States, the Copyright Act defines "derivative work" in 17 U.S.C. ยง 101:, in copyright law, a modification of an original work
- Formal derivative In mathematics, the formal derivative is an operation on elements of a polynomial ring or a ring of formal power series which mimics the form of the derivative from calculus. Though they appear similar, the algebraic advantage of a formal derivative is that it does not rely on the notion of a limit, which is in general impossible to define for a, in mathematics, an operation on elements of a polynomial ring which mimics the form of the derivative from calculus
- Aeroderivative gas turbine, a mechanical drive gas turbine derived from an aero engine gas turbine

- Derived In phylogenetics, a trait is derived if it is present in an organism, but was absent in the last common ancestor of the group being considered. This may also refer to structures that are not present in an organism, but were present in its ancestors, i.e. traits that have undergone secondary loss. Here the lack of a structure is a derived trait, in phylogenetics, a trait present in an organism, but absent in the last common ancestor of its group
