Check out our Math Homework Helper for tips and tricks on how to tackle those tricky math problems. Save and categorize content based on your preferences. Since we seek to maximize the area, we must write the area in terms of the perimeter to achieve one single equation. The method of Lagrange multipliers, which is named after the mathematician Joseph-Louis Lagrange, is a technique for locating the local maxima and minima of a function that is subject to equality constraints. Optimization problems seek to maximize or minimize a function subject to constraints, essentially finding the most effective and functional solution to the problem.

Hydraulic radius is defined as the cross-sectional area divided by the wetted perimeter: There are four inputs for this calculation: Placeholders are added for the time being and will be used as variables in the optimization we will set up in a later step. Intuitively, we know that to minimize surface area, we should build a can that holds 1 liter of liquid. Additionally, Solver has optimized the values of the top width, height, and wall angle to some values. This tells us that if h=0, the maximum width possible is 200. Its 100% free. First create a function that represents the nonlinear constraint. To constrain this optimization problem, first click on the Add button on the right side of the Solver window to open the Add Constraint window: After the new window opens, the constrained cell is set as follows: In our case, the cell reference is the value of the cross-sectional area and the constraint is the value of the target area.
