We believe that free, high-quality educational materials should be available to everyone working to learn well. Method for Solving Optimization Problems in Calculus Step 1: Fully understand the problem Step 2: Draw a diagram Step 3: Introduce necessary variables Step. You will also be able to post any Calculus questions that you have on our Forum, and we'll do our best to answer them! We do use aggregated data to help us see, for instance, where many students are having difficulty, so we know where to focus our efforts. Your selections are for your use only, and we do not share your specific data with anyone else. Your progress, and specifically which topics you have marked as complete for yourself.Your self-chosen confidence rating for each problem, so you know which to return to before an exam (super useful!).Your answers to multiple choice questions.Once you log in with your free account, the site will record and then be able to recall for you: The question asked us to specify the garden’s dimensions, which we have provided. Find two positive numbers whose product is 750 and for which the sum of one and 10 times the other is a minimum. Finally, check to make sure you have answered the question as asked: $x$ or $y$ values, or coordinates, or a maximum area, or a shortest time, or. A rectangles perimeter is the sum of its sides, that is, 100m 2L + 2W. The examples in this section tend to be a little more involved and will often involve situations that will be more easily described with a sketch as opposed to the 'simple' geometric objects we looked at in the previous section. Note also that the total area of Sam’s garden must be $A = 400 \text \quad \cmark$ħ. Optimization Problems in Calculus: Steps. In this section we will continue working optimization problems. We’ve called the width of the garden x (the top and bottom portions of the fence), and the length of the garden y (the left and right sides). Draw a picture of the physical situation. Your first job is to develop a function that represents the quantity you want to optimize. (Link will open in a new tab.) Stage I: Develop the function. Material for the base costs 10 per square meter. The length of its base is twice the width. Exercises 4.9(b) 1) A rectangular storage container with an open top has a volume of 10m3. So the answer to the question is 2ft × 2ft × 6ft. We’ll use our standard Optimization Problem Solving Strategy to develop our solution. The volume will be 24ft3 and the height will be 6 feet. What are the dimensions of the planting area that will minimize Sam’s cost to build the fence? (You may leave your answer as a square root you don’t have to find a decimal result.) His next-door neighbor agrees to pay for half of the fence that borders her property Sam will pay the rest of the cost. Sam wants to build a garden fence to protect a rectangular 400 square-foot planting area. In the exercises, you will see a variety of situations that require you to combine problem-solving skills with calculus. What dimensions minimize the cost of a garden fence?
