Linear programming is mostly used in Mathematics and it can be apply in the various field of study. Step 1: Calculate the width at the bottom of the channel. Let's draw the important information out from the problem. A constraint can be placed on an objective cell, variable cell, or any cell in the worksheet. The CP method keeps track of which solutions remain The constraint function is y + 2t 7 = 0. It is often used in portfolio management and asset allocation, as it can help to identify the best mix of investments for any given set of constraints. 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.
