    Synonyms: reflex, descendant#Noun
    Antonyms: etymon
    Hyponym: cognate
  3. (finance) A financial instrument whose value depends on the valuation of an underlying asset; such as a warrant, an option etc.
  4. (chemistry) A chemical derived from another.
  5. (calculus) One of the two fundamental objects of study in calculus (the other being integration), which quantifies the rate of change, tangency, and other qualities arising from the local behavior of a function.
    1. (Of a function of a single variable f(x)) The derived function of f(x): the function giving the instantaneous rate of change of f; equivalently, the function giving the slope of the line tangent to the graph of f. Written f'(x) or \frac{df}{dx} in Leibniz's notation, \dot{f}(x) in Notation_for_differentiation#Newton's_notation (the latter used particularly when the independent variable is time).
      The derivative of x^2 is 2x; if f(x) = x^2, then f'(x) = 2x
    2. The value of such a derived function for a given value of its independent variable: the rate of change of a function at a point in its domain.
      The derivative of f(x)=x^3 at x=2 is 12.
    3. (Of more general classes of functions) Any of several related generalizations of the derivative: the directional derivative, partial derivative, Fréchet derivative, functional derivative, etc.
    4. (generally) The linear operator that maps functions to their derived functions, usually written D; the simplest differential operator.
