So here's the clever trick: use the Lagrange multiplier equation to substitute ∇f = λ∇g: But the constraint function is always equal to c, so dg 0 /dc = 1. Thus, df 0 /dc = λ 0. That is, the Lagrange multiplier is the rate of change of the optimal value with respect to changes in the constraint.If we have more than one constraint, additional Lagrange multipliers are used. If we want to maiximize f(x,y,z) subject to g(x,y,z)=0 and h(x,y,z)=0, then we solve ∇f = λ∇g + µ∇h with g=0 and h=0.

6 years ago. There's a mistake in the video. y == lambda is the result of assumption that x != 0. So when we consider x == 0, we can't say that y == lambda and hence the solution of x^2 + y^2 = 0 is impossible. Instead we get this: - Assume x == 0. - Then either lambda == 0 or y == 0 or both.Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this siteLagrange Multipliers.
