de·riv·a·tive

(dĕ-riv'ă-tiv),
1. Relating to or producing derivation.
2. Something produced by modification of something preexisting.
3. Specifically, a chemical compound that may be produced from another compound of similar structure in one or more steps, as in replacement of H by an alkyl, acyl, or amino group.

derivative

/de·riv·a·tive/ (dĕ-riv´ah-tiv) a chemical substance produced from another substance either directly or by modification or partial substitution.

derivative

[dəriv′ətiv]
Etymology: L, derivare, to turn away
anything that originates in another substance or object. For example, organs and tissues are derivatives of the primordial germ cells. Chemical derivatives may be produced to confirm identification of a compound or to aid in the analysis of a compound.

derivative

the result of the calculation (usually with calculus) of the change of one variable with respect to another. Also alludes to the number of 'steps' of calculus required (e.g. acceleration is the second derivative of displacement with respect to time). See also differentiation.

Differentiability assumptions that had been expurgated earlier from economic theory when they were irrelevant were essential now for the generic discreteness of the set of equilibria.
20) This assumption is directly related to the question of the differentiability of the solution that we disposed of in Section 3.

In this edition, approximately 60 new exercises have been added, many taken from Problems in Mathematical Analysis by Kaczor and Nowak, and the chapters on infinite summations, differentiability and continuity, and convergence of infinite series have been reorganized.
But it requires the differentiability of f(x, [alpha]) and g(x, [alpha]) in x and the differentiability of g(x, [alpha]), [f.
To understand why differentiability makes such a difference, consider the necessary conditions for social optimum in the differentiable and the nondifferentiable case.
With appropriate differentiability properties the two definitions will have the same result and in this work we shall treat them as equivalent.
We believe that the potency and differentiability of our product candidates validate Curis's approach to developing novel anti-cancer agents and continue to demonstrate that our proprietary and partnered platforms are based on strong scientific rationale.
