19 kwi 2021 · Let $\size x$ be the absolute value of $x$ for real $x$. Then: $\dfrac \d {\d x} \size x = \dfrac x {\size x}$ for $x \ne 0$. At $x = 0$, $\size x$ is not differentiable. Corollary. Let $u$ be a differentiable real function of $x$. Then: $\dfrac \d {\d x} \size u = \dfrac u {\size u} \dfrac {\d u} {\d x}$ for $u \ne 0$.
Key points. Price elasticity measures the responsiveness of the quantity demanded or supplied of a good to a change in its price. It is computed as the percentage change in quantity demanded—or supplied—divided by the percentage change in price.

The rst-order conditions for maximizing this integrand, at any time t 2 (t0; t1), are found by di erentiating partially: w.r.t. C(t) to obtain e rtu0(C(t)) = p(t); w.r.t. K(t) to obtain _p(t) = p(t) f 0(K(t)); There is also the equality constraint K(t) _ = f (K(t)) C(t).
18 sie 2023 · In economics, the absolute value can represent the deviation of a certain quantity from an ideal or target value. For purposes of optimization, the derivative can be quite useful in determining how this deviation changes.
21 cze 2017 · $\begingroup$ The absolute value function has a derivative(s) on restricted domains. i.e. f'(x) = -1 for x <0 and f'(x) = 1 for x > 0. However, the absolute value function is not "smooth" at x = 0 so the derivative at that point does not exist. $\endgroup$
2 lip 2019 · How To Calculate The Derivative of Absolute Value. Derivatives are functions of a single variable at a certain value, and a derivative represents the slope of the tangent line about the function graph at the chosen point. Derivatives represent a basic tool used in calculus.
