Video Tutorial w/ Full Lesson & Detailed Examples (Video) Optimization Problems in Calculus: Steps. So, together we will work through numerous questions where we will have to follow the optimization problem-solving process to find the values that will either maximize or minimize our function. This means that the dimensions of the least costly enclosure are 20 feet long and 30 feet wide. Now all that is left to do is substitute our y-value into our secondary equation to find the x-value. Minimize or maximize a function for global and constrained optimization and local. The second derivative is positive at y = 30, so we know that we have a local minimum! Get answers to your optimization questions with interactive calculators. Now we will substitute our secondary equation into our primary equation ( the equation we want to minimize) and simplify. What are the two numbers?įirst, we need to find our primary and secondary equations by translating our problem. Suppose we are told that the product of two positive numbers is 192 and the sum is a minimum. Let’s look at a few problems to see how our optimization problem-solving strategies in work. While this may seem difficult at first, it’s really quite straightforward as we are simply finding two equations, plugging one equation into the other, and then taking the derivative. Step 4: Verify our critical numbers yield the desired optimized result (i.e., maximum or minimum value). Step 3: Take the first derivative of this simplified equation and set it equal to zero to find critical numbers. Step 2: Substitute our secondary equation into our primary equation and simplify. Step 1: Translate the problem using assign symbols, variables, and sketches, when applicable, by finding two equations: one is the primary equation that contains the variable we wish to optimize, and the other is called the secondary equation, which holds the constraints. Solving Optimization Problems (Step-by-Step) It is our job to translate the problem or picture into usable functions to find the extreme values. ![]() Optimization is the process of finding maximum and minimum values given constraints using calculus.įor example, you’ll be given a situation where you’re asked to find: ![]() Or, on the flip side, have you ever felt like the day couldn’t end fast enough?īoth are trying to optimize the situation!

The objective function is the formula for the volume of a rectangular box: Step 2: Create your objective function and constraint equation What are the dimensions of the tank? Step 1: Draw a picture and label the sides with variables You want to maximize the volume of the tank, but you can only use 192 square inches of glass at most. The tank needs to have a square bottom and an open top. You're in charge of designing a custom fish tank. Review problem - maximizing the volume of a fish tank We have a piece of cardboard that is 50 cm by 20 cm and we are going to cut out the corners and fold up the sides to form a box. ![]()
