optimization math ia example

38) Friendly numbers, Solitary numbers, perfect numbers. 41) Finding the volume of a rugby ball (or American football). Does finger length predict mathematical ability? Try to plot the locus of a sliding ladder. Solving the constraint for \(h\) and plugging into the equation for the printed area gives. Having these limits will also mean that we can use the process we discussed in the Finding Absolute Extrema Before starting the solution let’s first address the fact that we are using liters for volume. The first step in all of these problems should be to very carefully read the problem. For example, Mod 3 means the remainder when dividing by 3. Quadratic regression and cubic regression. 14/20 IA SL IA; Submitted December 6, 2018. However, if we solve the constraint for one of the two variables we can substitute this into the area and we will then have a function of a single variable. There is also the problem of identifying the quantity that we’ll be optimizing and the quantity that is the constraint and writing down equations for each. This is a fantastic 70 page booklet explaining different modelling methods from Moody’s Mega Maths Challenge. 6) Handshake problem: With n people in a room, how many handshakes are required so that everyone shakes hands with everyone else? – Playing around with multiplicative persistence – can you break the world record? Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. Use computer graphing to investigate. Doing this may not seem like all that great of a thing to do, but it can, on occasion, lead to a nice reduction in the amount of work that we need to do in later steps. 14)The Poincare Conjecture and Grigori Perelman – Learn about the reclusive Russian mathematician who turned down $1 million for solving one of the world’s most difficult maths problems. How to use graphic software to make art from equations. 1) The Monkey and the Hunter – How to Shoot a Monkey – Using Newtonian mathematics to  decide where to aim when shooting a monkey in a tree. This just means that we have one less equation to worry about. Can all fractions with a numerator of 2 be written as 2 Egyptian fractions? If \(f''\left( x \right) < 0\) for all \(x\) in \(I\) then \(f\left( c \right)\) will be the absolute maximum value of \(f\left( x \right)\) on the interval \(I\). 25) Euler’s 9 Point Circle. In this problem we want to maximize the area of a field and we know that will use 500 ft of fencing material. This will in turn give a radius and height in terms of centimeters. In this section we are going to look at another type of optimization problem. Go back to the figure at the start of the solution and notice that we can quite easily find limits on \(h\). 9) Designing bridges – Mathematics is essential for engineers such as bridge builders – investigate how to design structures that carry weight without collapse. How strange things happen when we start to manipulate divergent series. Model your data using a normal distribution. In this section we are going to look at optimization problems. 3) Stacking cannonballs – solving maths with code – how to stack cannonballs in different configurations. Create a free website or blog at WordPress.com. Some nice examples of using polar coordinates to create interesting designs. We need an interval of possible values of the independent variable in function we are optimizing, call it \(I\) as before, and the endpoint(s) may or may not be finite. 3) Benford’s Law – using statistics to catch criminals by making use of a surprising distribution. ( Log Out /  This topics provides a fascinating introduction to both combinatorial Game Theory and Group Theory. The constraint will be some condition (that can usually be described by some equation) that must absolutely, positively be true no matter what our solution is. Can you find the pattern behind it? 17) Does sacking a football manager affect results? Similarly, if we know that to the left of \(x = c\) the function is always decreasing and to the right of \(x = c\) the function is always increasing then the absolute minimum of \(f\left( x \right)\) in \(I\) will occur at \(x = c\).
