(M6E5) [Microeconomics] Cost Minimization Problem

In this episode I describe the Cost Minimization Problem in case of two inputs and show how we solve for optimal cost functions.
It's crucial to watch lecture videos in the proper order to ensure effective learning. This is because the concepts in each video build upon those introduced in previous videos. To help you with this, I recommend visiting my website, www.selcukozyurt.com, for a recommended course outline.

May i know why the Lagrange is + to Lamda?
because it's usually negatif
Thanks

It really doesn't matter: Both + and - are fine. But then you have to be careful about how you write your constraint f(x)=a: You can write it as f(x) - a or as a - f(x).
