Using Lagrange Multipliers In Exercises 13-18, use Lagrange multipliers to find the indicated extremum. Assume that x, y, and z are positive. See Example 1.

Maximize  f ( x , y , z ) = 3 x + 2 y + z

Constraint : 3 x 2 + y 2 + z 2 = 6

To determine

To calculate: The maximum of the function f(x,y,z)=3x+2y+z subjected to the constraint

g(x,y,z)=3x2+y2+z26.

Explanation

Given Information:

The function f(x,y,z)=3x+2y+z subject to the constraint g(x,y,z)=3x2+y2+z26 and x, y, z are positive numbers.

Formula used:

If f(x,y,z) has a maximum or minimum subject to the constraint g(x,y,z)=0, then it will

occur at one of the critical points of the function F defined by:

F=f(x,y,z)λg(x,y,z)

The variable λ is called the Lagrange Multiplier. To find the maximum or minimum of f follow

the given steps:

Step 1: Solve the following system of equations:

Fx(x,y,z,λ)=0Fy(x,y,z,λ)=0Fz(x,y,z,λ)=0Fλ(x,y,z,λ)=0

Step 2: Evaluate f at each solution point obtained in the first step. The greatest value yields maximum of f and the smallest value yields minimum of f subject to the constraint g(x,y,z)=0.

Calculation:

Consider the given equations,

f(x,y,z)=3x+2y+z and g(x,y,z)=3x2+y2+z26

Now, consider the primary equation,

F=f(x,y,z)λg(x,y,z)F=(3x+2y+z)λ(3x2+y2+z26)

For critical numbers of F, differentiate F with respect to x,y,z. then set it equal to zero
