Lagrange Multipliers #2: Two Variables, 1 Constraint

[@itsadam4316]

You're honestly a life safer. So clear with every step and you broke down something very daunting into a bunch of simple steps.

[@williamramsfeldt201]

Thank you! Very clear example and easy to follow. Helped me with my own problem.

[@turksvids]

Glad it helped! Lagrange multipliers is definitely one of the tricky topics you run into.

[@jamessullivan9363]

thank you for a good example with such clear work

Great video, easy to follow along!

A very Great piece.

I have a hard time with this. Sometimes you solve the system of eqs with respect to lambda and sometimes with x and y. I am not sure when to choose which. Can the lambda ever equal zero when calculating lagrange multipliers?

[@turksvids]

Yeah, the hard part of Lagrange Multipliers is really solving the system. For my purposes I almost never need to know the value of lambda so I usually try to solve equal equation for lambda and then set those equations equal to each other. Unfortunately there's not really a hard fast rule of what to do.

How to apply this on functions like 3x^2 + 4xy + y^2. like when xy are together multiplied.....solving the system of equations then becomes a real challenge ! any idea ?
