Special functions ( scipy.special ) Integration ( scipy.integrate ) Optimization ( scipy.optimize ). 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. Two final questions, these are really important does my answer make sense? You want to do a reality check in the end does your answer actually make sense? And did I answer the question asked? This is really important in any problem but especially with optimization problems it's very easy to answer the wrong question you want to make sure that if they asked for what is the maximum quantity you give the maximum quantity and not merely where it occurs that sort of thing. The volume will be 24ft3 and the height will be 6 feet. You can use the first derivative test for absolute max mins or the second derivative test for absolute max mins depending on you might want to chose which one of these you use depending on how easy it is to actually calculate the second derivative. If you do have feasible domain which is a closed bounded interval you can use the closed interval method which is an easy method and that's why you might want to prefer that. And then over here we have 3 optimization methods that we've studied you can choose from any of these depending on what seems appropriate for the problem. So the feasible domain will be the domain of the function of the quantity to be optimized. You want to identify the feasible domain this is important because it determines the method that you're going to use to optimize the problem if you can make it so that the feasible domain is a closed interval for example you can use the closed interval method. First steps in any optimization problems regardless of whether it's Economics or anything else, you want to identify the quantity to be optimized so read the problem carefully for clues as to what exactly is maximized or minimized. Vector calculus is a branch of mathematics concerned. Multivariable calculus is the extension of calculus in one variable to functions of several variables. Calculus has two primary branches: differential calculus and integral calculus. Now what quantities are optimizing the economics? We can minimize costs or maximize revenue we can also maximize profit. Calculus is a branch of mathematics focused on limits, functions, derivatives, integrals, and infinite series. First of all let me remind you what optimization is, optimization means finding the maximum or minimum values of a quantity, or finding when these max mins occur. ![]() At other times, the constraints of a problem introduce right triangles (where the Pythagorean Theorem applies) or other functions whose formulas provide relationships among the variables.I want go talk about the kinds of optimization problems that are going to come up in Economics. Notes on Calculus and Optimization 1 Basic Calculus 1.1 Denition of a Derivative Let f(x) be some function of x, then the derivative of f, if it exists, is given by the following limit df(x) dx lim h0 f(x+h)f(x) h (Denition of Derivative) although often this denition is hard to apply directly. Sometimes those involve perimeter, area, volume, or surface area. This 292-lesson course includes video and text explanations of everything from Calculus 1, and it includes 76 quizzes (with solutions) and an additional 19 workbooks with extra practice problems, to help you test your understanding along the way. ![]()
