Problems with Lagrange Multipliers

  1. Apr 14, 2012 #1
    Does anyone have any tips for solving the system of equations formed while trying to find Lagrange Multipliers? I have searched for videos online (patrickjmt and the MIT lecture on Lagrange Multipliers) but I still find it a bit confusing.

    It is, as you can imagine, impossible to give anything that will work for all Lagrange multiplier problems but here is something I have found useful: since the equations can all be put into the form "[itex]f= \lambda g[/itex]" and a value of [itex]\lambda[/itex] is not part of the solution, start by eliminating [itex]\lambda[/itex] by dividing equations.
