So, the largest value of A occurs at w=100 where A=20,000 ft2. Step 2: Now find the gradients of both functions. To solve an optimization problem, you must set up a function in terms of known values and variables. To use this tool, you need a function that is an objective function and constraint in the form of an equation in the area where you want to find its optimal values. The First Derivative Test for Absolute Extrema Values states that for a critical point c of a function f on an interval: if f'(x)>0 for all xc, then f(c) is the absolute maximum value of f(x), if f'(x)<0 for all x0 for all x>c, then f(c) is the absolute minimum value of f(x). However, the baseline procedure is similar for all optimization problems. I hope it keeps getting better too. For example, in Example 2.25 we showed that the constrained optimization problem Maximize : f(x, y) = xy given : g(x, y) = 2x + 2y = 20 had the solution (x, y) = (5, 5), and that = x 2 = y 2. However, the baseline procedure is similar for all optimization problems. In this case, we solved for the variable h to write the area equation in terms of width.
