    Need help understanding Lagrange multipliers at a more fundamental level.

    Nevermind. I understand now. I spent 2 seconds on the wikipedia page for it, and I finally had that "Oh my God. I get it." moment.

    Need help understanding Lagrange multipliers at a more fundamental level.

    So, is the max and min found a max and min based on the constraint, and not a regular max/min of f(x,y) or f(x,y,z) ?

    Need help understanding Lagrange multipliers at a more fundamental level.

    I understand that for Lagrange multipliers, ∇f = λ∇g And that you can use this to solve for extreme values. I have a set of questions because I don't understand these on a basic level. 1. How do you determine whether it is a max, min, or saddle point, especially when you only get one...

    Converting an Integral to a Rieman Sum

    I know I should know this, but how would one convert a typical integral into a Rieman Sum? ∫0n sinx + x dx for whatever n. for example.
