Question

Find the maximum and minimum values of f(x,y)=81x2+y2f(x,y)=81x2+y2 subject to the constraint 4x2+y2=94x2+y2=9.

Answer #1

Use Lagrange multipliers to find the maximum and minimum values
of f(x,y)=4x3+y2 subject to the constraint 2x2+y2=1 also, find the
points at which these extreme values occur.

Find the minimum and maximum values of the function f(x,y)=x2+y2
subject to the constraint x4+y4=2592 Use the Lagrange equations

Use Lagrange multipliers to find the maximum and minimum values
of f(x,y)=x2+5y
subject to the constraint x2-y2=3 , if
such values exist.
Maximum =
Minimum

Find the maximum and minimum values of the following function,
subject to the given constraint. Maximize and minimize the function
f(x, y) = xy2 subject to the constraint x2 + y2 = 1.
maximum of ____at (x, y) = (____,_____)
minimum of _____ at (x, y) = (_____,____)

Find the indicated maximum or minimum value of f subject to the
given constraint. Maximum: f(x,y,z) = (x2)(y2)(z2); x2 + y2 + z2
= 6

Find the minimum and maximum values of the function
f(x,y)=x2+y2f(x,y)=x2+y2 subject to the given constraint
x4+y4=2x4+y4=2.
(The minimum is not not zero, DNE, or NONE, I have tried all of
those)

Find the relative minimum value of
f(x,y)=4x2 +4y2 -2xy,
subject to the constraint
x+y=4.
The value is f(_,_)= _
