Optimization - Minimum sum of two numbers

[@renevanwyk4053]

Thank you!!! The first video I found which clearly explains the difference between minimum and maximum critical values.

[@AdamsAppleseed]

8:28 could someone explain that? Idk how you can just say that if the second derivative is positive, you got a minimum...

[@Cameron-rc5ef]

It means that the critical point is a local min so it has to be minimum

[@tmdsb2655]

What if you get maximum instead???

[@Dippa1991]

TMD SB then you may of made an error in your previous calculations
