Derivative of product notation
http://cs231n.stanford.edu/vecDerivs.pdf 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

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.

Given two differentiable functions, f (x) and g (x), where f' (x) and g' (x) are their respective derivatives, the product rule can be stated as, or using abbreviated notation: The product rule can be expanded for more functions.
Web1. Can someone explain how to differentiate something like. ∏ i < j N ( x i − x j) with respect to x i. The product starts from 1 and goes to N. I started off by ignoring the x j as it …
WebThe rule can be proved by using the product rule and mathematical induction . Second derivative [ edit] If, for example, n = 2, the rule gives an expression for the second derivative of a product of two functions: More than two factors [ edit] The formula can be generalized to the product of m differentiable functions f1 ,..., fm .
