In this chapter, we prove the chain rule for functions of several variables and give a number of applications. Among them will be several interpretations for the gradient. These form one of the central points of our theory. They show how powerful the tools we have accumulated turn out to ...
chain rule(redirected from Chain rule (several variables))Also found in: Encyclopedia. chain rulen (Mathematics) maths a theorem that may be used in the differentiation of the function of a function. It states that du/dx = (du/dy)(dy/dx), where y is a function of x and u a ...

Tags Chain Chain rule Functions Variables In summary, The conversation discusses the use of the chain rule in finding partial derivatives. The equations (A) and (B) are derived using the chain rule, and (C) and (D) are obtained by solving for dV/dx and dV/dy. The partial derivatives ...
4. 3. The Multivariate Chain Rule In the multivariate chain rule (or multivariable chain rule) one variable is dependent on two or more variables. The chain rule consists of partial derivatives. For the function f(x,y) where x and y are functions of variable t, we first differentiate th...
In 1970, several interesting new summation formulas were obtained by using a generalized chain rule for fractional derivatives. The main object of this paper is to obtain a presumably new general formula. Many special cases involving special functions of mathematical physics such as the generalized ...
The chain rule for multivariable functions where the variables are themselves multivariable functions is then explained; and to illustrate this general form of the chain rule we study several examples in detail. 1. Chain Rule Recall that the chain rule for functions of a single variable gives the...

To simplify the simulation process and understand the influence of the two variables on the profits of the supply chain members, this study assumes that their values are fixed. It also assumes that the probability density functions of demand 𝑥𝑖xi are independent and follow normal distribution...
