# Math Help - Lagrange Multipliers in 4D

1. ## Lagrange Multipliers in 4D

We have:

$
\nabla f=\lambda g
$

$g=c$

Where is the function we want to minimise/maximise and g=c is the condition. Does this hold for 4 variable i.e. in 4D.

It holds for any dimension... Lagrange multipliers - Wikipedia, the free encyclopedia
