The upshot of all this is the following: at a local maximum, the gradient of f f and the gradient of g g are pointing in the same direction. In other words, they are proportional. In other words, there's some constant λ λ such that the gradient of f f is λ λ times the gradient of g g. That's it.g (x, y, z) = 2x + 3y - 5z. It is indeed equal to a constant that is ‘1’. Hence we can apply the method. Now the procedure is to solve this equation: ∇f (x, y, z) = λ∇g (x, y, z) where λ is a real number. This gives us 3 equations and the fourth equation is of course our constraint function g (x, y, z).Solve for x, y, z and λ.Courses on Khan Academy are always 100% free.
