Lecture 9: Partial derivatives If f(x,y) is a function of two variables, then ∂ ∂x f(x,y) is defined as the derivative of the function g(x) = f(x,y), where y is considered a constant. It is called partial derivative of f with respect to x. The partial derivative with respect to y is defined similarly. We also use the short hand notation ...

PARTIAL DERIVATIVES AND THEIR APPLICATIONS 4 aaaaa 4.1 INTRODUCTON: FUNCTIONS OF SEVERAL VARIABLES So far, we had discussed functions of a single real variable defined by y = f(x).Here in this chapter, we extend the concept of functions of two or more variables.

this chapter several applications of partial differentiation to business and economies are discussed. For example. if L units of labour and K units of capital are used to produce P units products then the function P J' (L, K) is called a production function and its partial derivatives are called mtuginal pmductivitv functions.

The \mixed" partial derivative @ 2z @x@y is as important in applications as the others. It is a general result that @2z @x@y = @2z @y@x i.e. you get the same answer whichever order the difierentiation is done. 0.8 Example Let z = 4x2 ¡ 8xy4 + 7y5 ¡ 3.

Partial Derivatives Examples And A Quick Review of Implicit Differentiation Given a multi-variable function, we defined the partial derivative of one variable with respect to another variable in class. All other variables are treated as constants. Here are some basic examples: 1. If z = f(x,y) = x4y3 +8x2y +y4 +5x, then the partial ...

APPLICATIONS OF DERIVATIVES Derivatives are everywhere in engineering, physics, biology, economics, and much more. In this chapter we seek to elucidate a number of general ideas which cut across many disciplines. Linearization of a function is the process of approximating a function by a line near some point.
