Quick Math Question - Lagrangian
Okay so basically I have a function f(x,y)=0
And I want to find an x and y that satisfy the above equation that minimises the function g(x,y) Seams easy, but I've totally forgotten how to do this. Something to do with Lagrangian or something? It sucks realizing how much I've forgotten since University |

Re: Quick Math Question - Lagrangian
eh, it so happens I can write f(x,y) as y = j(x) so I can do this now
still curious as to how to do it in general though if anyone knows |

Calculus of variations. You want to find a function such that the functional is minimized.

You mean "Lagrange Multipliers"; link: http://en.wikipedia.org/wiki/Lagrange_multipliers [/ QUOTE ] sweet, that's it |
