08.11.2019 · This calculus 3 video tutorial provides a basic introduction into lagrange multipliers. It explains how to find the maximum and minimum values of a function...

02.12.2019 · Section 3-5 : Lagrange Multipliers. In the previous section we optimized (i.e. found the absolute extrema) a function on a region that contained its boundary.Finding potential optimal points in the interior of the region isn’t too bad in general, all that we needed to do was find the critical points and plug them into the function.

For Lagrange multipliers, we will call this constant (lambda). We will equate the gradient of our surface rf with the gradient of a curve rg: rf = rg This will force us to find a point where the level curves of f (in red) are tangent to the curve g (in blue). 148 of 157.

For a given perimeter, what is the greatest possible area of a rectangle with that perimeter? We can formulate this as a Lagrange multiplier ...

Often the Lagrange multipliers have an interpretation as some quantity of interest. For example, by parametrising the constraint's contour line, that is, if the Lagrangian expression is then So, λk is the rate of change of the quantity being optimized as a function of the constraint parameter. As examples, in Lagrangian mechanicsthe equations of motion are derived by findin…

If we have more than one constraint, additional Lagrange multipliers are used. If we want to maiximize f(x,y,z) subject to g(x,y,z)=0 and h(x,y,z)=0, then we solve ∇f = λ∇g + µ∇h with g=0 and h=0.
