IA Idea 2 - Modeling Statistics Modeling IAs can generally refer to any project where a certain change in statistics is being presented in a visual manner. One example is modeling the radioactive decay of chernobyl, and determining if conditions are suitable for living. However, redoing them would not be such a bad idea as long as you ensure that you infuse some complexity, personal involvement and more critical thinking. Linear Model Equation & Examples in Real-Life | What is a Linear Model? Use different methods to see which one works and which one doesnt. Even if they do understand the mathematics, the restriction on length does not allow such students to address the target audience when explaining the mathematics. In this video. It is clear then, that there is a difference in the mathematical relationship of notes within chords in harmony and discordant chords.

The mathematical nature of the notes in traditional harmony suggests that the sound waves are more pleasing to our brain because of the way the notes fit together. 23) Perfect Numbers: Perfect numbers are the sum of their factors (apart from the last factor). This is the house the client should buy! Straight lines are not straight, parallel lines meet and angles in a triangle dont add up to 180 degrees. There is a $1 million prize for solving the Riemann Hypothesis and $250,000 available for anyone who discovers a new, really big prime number. Choose your own pattern investigation for the exploration. These waves look very similar to the major chord waves, as only one note has changed; the C# has gone down by a semitone. So there we have it: 50 IB Maths IA topic ideas to give you a head-start for attacking this piece of IB coursework! % She currently teaches struggling STEM students at Lane Community College. Understanding What Math IA is All About Students are required to investigate an area of mathematics and then present it as a written body of work. This is the same method as that of the difference of means test and the only distinction is on the equations. IA. Because the three distances are changing in time, they are functions of t. Differentiate for t the relation obtained above. This investigation was very limited, as I was not able to research properly how electronic instruments work, and how they differ from mechanical instruments. 41) Arithmetic number puzzle It could be interesting to do an exploration where you solve number problems like this one.

The following ' SUVAT' displacement formula and the Kinematics initial velocity formulae will be used as a medium. Afterward, calculate the average of all of those proportions for the whole season. 4 0 obj This produces the following graph: Using an A major chord, I can look at the relationship between the notes in a major chord. The next step in this process is to do the math. These ideas need to be conveyed in your writing. Again using an A chord, I have modeled a minor chord and looked at its features. This is a lovely result which uses parametric functions to create a beautiful example of mathematical art. It is therefore more complicated than the difference of means test. How many different ways can we use to solve a number theory problem?

This chord is also known as The Devils Chord, as it is considered to be the most the unpleasant sounding chord in music. All rights reserved. Recently, computer modeling has become a popular method for understanding large data sets and for running statistical analysis such as using Bayes' formula. I decided to use Middle A(A. << /Type /Page /Parent 3 0 R /Resources 6 0 R /Contents 4 0 R /MediaBox [0 0 612 792] 5 Algebra and number. In this chord, the gaps in the ratios are not easily relatable to each other, suggesting that discordant sets of notes are not as natural as those that sound harmonic. This section looks at the quality of the maths and how relevant it is to the exploration. So there we have it, a well organized exploration of the idea and IB layout of your Mathematics IA! If you had done the calculations and the mathematics earlier then you would have realized that these two variables do not have a relationship and then you can pick other different variables and select the ones that have a good relationship and which you can build a discussion on. Unfortunately these equations are very difficult to solve - but luckily we can use a computer program to plot what happens. The ratio of the gaps is now 2:3:5. Save my name, email, and website in this browser for the next time I comment. Try to plot the locus of a sliding ladder. Related rates are used to find how two rates of change are related. The second criterion looks largely at the mathematical language you have used, such as: Ensure that these three components are accurate and consistent throughout your IA. There are two fundamental questions that you can ask yourself at the beginning of this process. How all our digital communications are kept safe through the properties of primes. 6) Continued fractions: These are fractions which continue to infinity. {eq}A = 25 * 55 = 1375 {/eq} square feet. The mathematical model definition is that a mathematical model is a quantitative description of a system. 408 There are many different uses for mathematical models such as understanding relationships or making predictions about the future, and there are many different types of mathematical models that can be used depending on the needs of the scientist. Updated: 01/07/2022 Table of Contents. = -1/12 ? 49) Rational approximations to irrational numbers. Figure 3: A graph is a visual representation of a system. You can go to gapminder.org and go through the data they have. The Pythagorean theorem states that the square of the hypotenuse in a right triangle equals the sum of the squares of the legs. 2 0 obj A pivotal point to consider is the level and clarity of the mathematics you use - the IB rewards a lot of marks for the use and communication of Mathematics, so keep this in mind when you start writing your Maths IA up! There has been a recent breakthrough in this problem. 2) Gravity, orbits and escape velocity Escape velocity is the speed required to break free from a bodys gravitational pull. I decided to use Middle A, I altered the wavelengths, or frequencies, of the graphs by changing the coefficient of x. 2) Solving maths problems using computers computers are really useful in solving mathematical problems. 2) Goldbachs conjecture: Every even number greater than 2 can be expressed as the sum of two primes. One of the great unsolved problems in mathematics. 39) Zenos Paradox Achilles and the Tortoise A look at the classic paradox from ancient Greece the philosopher proved a runner could never catch a tortoise no matter how fast he ran. It is essential that you select the appropriate topic for you that aligns with your interests and you dont pick a topic just because very many people have done it. A first inversion chord starting on A will actually be in the key of F major. How can we use computers to gain a deeper understanding of sequences? Equation 1: y=sinx Equation 2: y=sin (554.37/440x) Equation 3: y=sin (659.26/440x) Equation 4: y=sin2x ( A.
