Wow. I couldn't perceive till I see from this lect. that the Lagrange multiplier method, example, that the maximum values of f are found at infinity to the hyperbola.
this is all good but maybe breaking up the lecture into sections and many different videos instead of 50 minutes would work great. but he teaches very well
He thinks it's funny that the girl is asking what the Lagrange multiplier is as if her question is why something that multiplies should be called a multiplier, when he never explicitly said what it was. The problem with this lecture is that it's not very focused and it's very easy to lose sight of the goal when he does it in such a scrambled way. I wouldn't be surprised if a quarter of that question-less silence is due to the inability to even formulate a question about the material.
Psh, that example had a much easier solution. Just multiply the first two equations, cancel the xy (as clearly neither can be 0), and you get L^2 = 4.
Glad to finally learn Lagrange Multipliers, though; my teacher skipped over them in AP Calc, so they've always seemed like some magical algorithm I would never know that trivially solves optimization problems.
proofs are something you can look up in the text book or online. for me, they are also something I see in regular lecture. it's nice that the MIT videos are straight to the point.
It's not a course on Analysis, but an introductory multivariable calculus. The first contact with the subject should be approached without very formal proofs. Other than that, many students will not follow a career on Math, that's why there are different subjects with different focus. MIT's approach on introductory courses are novel and enable the student to go further on his own, if desired.
wow. I asked my teacher how the Gradient of F or G related to the graph and he gave me a half ass'd answer. Now I finally get what it all means graphically and why the gradients are equal * lambda. THANKS!
So, what's the point? ;-)

guys does lagrange's method include every critical point on the curve ?

@middleCmusic Maybe it's because i already understand lagrange multipliers, but they should not be that lost. this explanation is pretty decent, imho
