Lagrange Multiplier where constraint is a rectangle

[QUOTE="stevendaryl, post: 5465078, member: 372855"] Just to add to what Ssnow said, I think that Lagrange multipliers are only directly useful for continuous constraints. If the constraint is just that [itex](x,y)[/itex] must be inside a rectangle, then I would think that you would do the following: [LIST=1] [*]First, find the extrema forgetting about the rectangle. [*]Then if the extrema found in step 1 are all inside the rectangle, then you're done. [*]If not, then use the method of Lagrange multipliers to find the extrema for each of the four sides of the rectangle. [/LIST] [/QUOTE]
