Linear regressions: Run linear regressions using OLS to predict and estimate the effect of one variable on another. Analysing Data: In the 200 meter dash, is there an advantage to a particular lane in track? An Augmented 6th is also known as a dominant 7th, which was one of the first discordant chords to be used in music in the West. To extend this investigation, I would like to look at the area between the waves in relation to the semitone difference and frequency ratios. 12) Four colour map theorem a puzzle that requires that a map can be coloured in so that every neighbouring country is in a different colour. Mathematics and photography: Exploring the relationship between the aperture of a camera and a geometric sequence, Normal Distribution: Using distributions to examine the 2008 financial crisis, Mechanics: Body Proportions for Track and Field events. This method is related to the difference of means test but the ANOVA test is involved with testing multiple means. Required fields are marked *. If you are interested in the NBA and lets say your favorite team is The Suns you can go to their website and check the proportions of the three-shot and the two-shots. So for instance you decided to correlate 2 things. This is why we allow the book compilations in this website. B. It is about evaluating the research to pick up on all evidence that goes beyond what a typical mathematical test would. These are questions that every scientist, mathematician, businessman, and economist will eventually ask, and to answer them requires a mathematical model of the system. 46) Ramanujans Taxi Cab and the Sum of 2 Cubes. 29) Classical Geometry Puzzle: Finding the Radius. 19) Natural logarithms of complex numbers. This assessment is a great way for students to expand their knowledge and learn valuable skills. Like almost all of your internal assessments, your Maths IA has to begin with a super clear introduction that sets the context and aim of the whole exploration. 7) Fibonacci sequence and spirals in nature There are lots of examples of the Fibonacci sequence in real life from pine cones to petals to modelling populations and the stock market. << /ProcSet [ /PDF /Text ] /ColorSpace << /Cs1 7 0 R >> /Font << /TT1 8 0 R The mathematics of deceit: How con artists use pyramid schemes to get rich quick! It needs to be independent and unique. 9) Polyominoes: These are shapes made from squares. Are you getting ready to present your Math IA? Erroneous notation, it should be 554.37x/440) I altered the wavelengths, or frequencies, of the graphs by changing the coefficient of x. The IB is measuring relevancy by checking that you only included maths that is directly intended to answer the research question. I started by working out how to model a single note. Minor chords are also considered to be in harmony. How big would the length of the basement have to get so that the area satisfied the client? Look out for these during the Winter and Easter breaks before the final exam. Many IB students find it hard to study mathematical concepts. This evidence would suggest that notes which are traditionally considered to be in harmony are mathematically neater than those that are not in harmony. 7) When do 2 squares equal 2 cubes? Recently, computer modeling has become a popular method for understanding large data sets and for running statistical analysis such as using Bayes' formula. Straight lines are not straight, parallel lines meet and angles in a triangle dont add up to 180 degrees. 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.

More computing led investigations. One travels north at 40 km/h, and the other travels east at 30 km/h. Because the three distances are changing in time, they are functions of t. Differentiate for t the relation obtained above. 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. With these Topics ensure that you are not heavily reliant on the Physics aspect; put more emphasis on Mathematics. What is a mathematical model? 10/29/2020. coursework science than the discordant notes. If you find yourself struggling with anything from finding a topic to writing your evaluation, here are the answers to 5 of the most frequently asked questions about the econ IAs, answered by expert IB graduates. Use Figure 4 to help the mayor find out how fast her town is growing. 16 Math IA Ideas I wanted to make the sound wave of this note equal to the sine wave, which meant making 220Hz equivalent to ( typing error). Equation 3: y=sin(659.26/440x) Using x'(t)=30, y'(t)=40 and the distance of each car after two hours, we obtain: 4. oZWE|-jT (XA Can you find the loop of infinite sadness? 31) The Shoelace Algorithm to find areas of polygons. 15 Closing. 10) Is Intergalactic space travel possible? endobj View Mark Scheme. 4.

Equation 2: y=sin(659.26/440x), (A,D. 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. The planets follow a surprising pattern when measuring their distances. 11) Understanding the fourth dimension: How we can use mathematics to imagine (and test for) extra dimensions. This section looks at the quality of the maths and how relevant it is to the exploration. A great introduction to some of the ideas behind non-euclidean geometry. 14, Advice from an IB Examiner on topics you should avoid. 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. A first inversion chord starting on A will actually be in the key of F major. Probability: Are Oxford and Cambridge biased against state-school applicants? However, this is just a theory and would have to be tested more thoroughly. Investigate what makes a number happy or sad, or sociable! Modeling of any kind as it also takes a lot of effort. Try to plot the locus of a sliding ladder. 45) The Mordell Equation. It covers what mathematical modeling is as well as different types of models in math. Two variable function . 2 0 obj 15) Julia Sets and Mandelbrot Sets We can use complex numbers to create beautiful patterns of infinitely repeating fractals. We've trained a system that solves grade school math problems with nearly twice the accuracy of a fine-tuned GPT-3 model.

Gini coefficient: Can you use integration to derive the gini coefficient for a few countries, allowing you to accurately compare their levels of economic inequality? Familiarise yourself with the steps below, and then dive into your chosen topic. These ideas need to be conveyed in your writing. A model in math can be different depending on the type of model or what the model is describing, and some of the uses of mathematical models are: An error occurred trying to load this video. This analysis can be done in minutes or hours, but without a computer the same analysis could take decades. I will now look at different chords to see if this conjecture holds true. = -1/12 ? 5) Stacking cannon balls: An investigation into the patterns formed from stacking canon balls in different ways. Therefore the graphs are very similar. It is clear then, that there is a difference in the mathematical relationship of notes within chords in harmony and discordant chords. 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. 13 40 Mathematics Internal Assessment Ideas. Or is it better to switch? Computer modeling may be new, but chemical formulas as a math model are centuries old. stream This particular problem was solved by Euler.
