Derivatives: definition and basic rules Khan Academy

In calculus, the product rule (or Leibniz rule or Leibniz product rule) is a formula used to find the derivatives of products of two or more functions. For two functions, it may be stated in Lagrange's notation as The rule may be extended or generalized to products of three or more functions, to a rule for higher-order … See more Discovery of this rule is credited to Gottfried Leibniz, who demonstrated it using differentials. (However, J. M. Child, a translator of Leibniz's papers, argues that it is due to Isaac Barrow.) Here is Leibniz's argument: Let u(x) … See more • Suppose we want to differentiate f(x) = x sin(x). By using the product rule, one gets the derivative f′(x) = 2x sin(x) + x cos(x) (since the derivative of x is 2x and the derivative of the See more Product of more than two factors The product rule can be generalized to products of more than two factors. For example, for three factors we have $${\displaystyle {\frac {d(uvw)}{dx}}={\frac {du}{dx}}vw+u{\frac {dv}{dx}}w+uv{\frac {dw}{dx}}.}$$ See more Limit definition of derivative Let h(x) = f(x)g(x) and suppose that f and g are each differentiable at x. We want to prove that h is differentiable at x and that its derivative, h′(x), … See more Among the applications of the product rule is a proof that $${\displaystyle {d \over dx}x^{n}=nx^{n-1}}$$ See more • Differentiation of integrals • Differentiation of trigonometric functions – Mathematical process of finding the derivative of a trigonometric function • Differentiation rules – Rules for computing derivatives of functions See more WebSep 30, 2016 · Notation with covariant/contravariant derivative with product rule.

The derivative of a product of more than two functions

WebThe derivative of a function is the ratio of the difference of function value f (x) at points x+Δx and x with Δx, when Δx is infinitesimally small. The derivative is the function slope or slope of the tangent line at point x. Second derivative The second derivative is given by: Or simply derive the first derivative: Nth derivative The original notation employed by Gottfried Leibniz is used throughout mathematics. It is particularly common when the equation y = f(x) is regarded as a functional relationship between dependent and independent variables y and x. Leibniz's notation makes this relationship explicit by writing the derivative as Furthermore, the derivative of f at x is therefore written WebApr 21, 2024 · edited Jul 8, 2024 at 11:10. , the number of functions. if , there is nothing to prove. if , then you just get the product rule. Assume the claim is true for functions, and prove it for +. Write = where 2.. f + 1. Now differentiate f 1 g using the product rule and apply the induction hypothesis to g ′.
