WebLagrange Multipliers. To find these points, we use the method of Lagrange multipliers : Candidates for the absolute maximum and minimum of f(x, y) subject to the constraint g(x, y) = 0 are the points on g(x, y) = 0 where the gradients of f(x, y) and g(x, y) are parallel. To solve for these points symbolically, we find all x, y, λ such that ∇ ... radius location
