2 Answers. Sorted by: 1. Well Lagrange multiplier will help you, but since you have 2 equations, you can easily to reduce the function to a one variable, which is easily to maximize or minimize. So from the two equations, you have: x = y + 7; and x = y + 7; and. x + 2y + z = 3 y + 7 + 2y + z = 3 z = −4 − 3y x + 2 y + z = 3 y + 7 + 2 y + z ...I need to use Lagrange Multipliers to find the maximum and minimum values of the function: f(x, y) = 2exy f ( x, y) = 2 e x y. subject to the given constraints: 2x2 +y2 = 32 2 x 2 + y 2 = 32.

Weighted percentages help in situations where certain factors are more important than others.And, of course, you don't need to use Lagrange multipliers, since you can eliminate the constraint by expressing one of the three variables in terms of the other two. However, I do believe you get simpler equations/expressions by keeping the Lagrangian form, but that is primarily a personal preference. RGV .
