to find the possible relative extrema of the function f(x,y) subject to the constraint g(x,y)=8, the lagrangian function based on the lagrange multiplier λ is given by....

  • calculus -

    solve the equations

    ∇f(x,y) = λ∇g(x,y)
    g(x,y) = 8

    plug in the solutions and pick the extrema.
