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?
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 ?
You're honestly a life safer. So clear with every step and you broke down something very daunting into a bunch of simple steps.
Thank you! Very clear example and easy to follow. Helped me with my own problem.
Glad it helped! Lagrange multipliers is definitely one of the tricky topics you run into.
thank you for a good example with such clear work
Great video, easy to follow along!
A very Great piece.
