# Lagrangian multipliers and drawing schemes

Not what you're looking for?

1) Who can explain me Lagrangian multipliers with drawings scheme etc...

1)I just can't imagine what is happening in space with Lagrangian multipliers.

2) I did this problem but here also I can't understand it, because I can't understand what is happening in space! could you explain it with drawings and schemes please : the atmospheric pressure in a region near the origin is given by the formula P=30+(x+1)(y+2)exp(z).

Approximately where is the point closest to the origin at which the pressure is 31.1 ?

This explains and shows how to use Lagrangian multipliers.

##### Solution Preview

1) Lagrangian multipliers are used in Lagrangian method, which is to minimize a function subject to some constraints.

If the problem is

min f(x)

subject to h(x)=0

then we set L(x,lamda)=f(x)-lamda*h(x) and want to find the minimum of L(x,lamda, where lamda is the Lagrangian multiplier. If we have k constraints, then we should have k Lagrangian multipliers.

We use Lagrangian method to transform a constraint-problem into unconstraint-problem.

I'm not sure about your first question, but I ...
