Chapter 9: Further Applications of the Derivative Section 1: Optimization Problems Section 2: Business and Economics Applications Objectives: \\/ Solve real-life optimization problems \\/ Solve business and economics optimization problems Steps for Optimizing: Example 1: Find two positive numbers satisfying the given requirements. The sum of the first and twice the second is 100 and the product is a maximum. Primary Equation: Secondary Equation: Use the Secondary Equation to rewrite the Primary Equation so that it is in a single variable. Use calculus to find the two positive numbers that will maximize the product. 1 I 'I'I'at'y Cools Mull] I217: limit Calculus N'l'il 'J.l-2 Example 2: A dairy farmer plans to enclose a rectangular pasture adjacent to a river.
