All rights reserved. 12) The Riemann Sphere an exploration of some non-Euclidean geometry. 22) The Folium of Descartes. IB Math IA Examples and Ideas IA Idea 1 - Modeling Statistics Modeling statistics is a pretty broad concept for an IA, but it can refer to any project where a change in statistics is presented in a visually effective manner. Example 1: Use the kinematic equation {eq}v_f = v_i + at {/eq} where {eq}v_f {/eq} means final velocity, {eq}v_i {/eq} means initial velocity, a stands for acceleration, and t stands for time to answer the following question: A race car driver sits at the starting line. Ib Math Studies Ia Thesis Example When somebody should go to the ebook stores, search initiation by shop, shelf by shelf, it is truly problematic. An interesting insight into the mathematical field of Number Theory. The given equation, {eq}v_f = v_i + at {/eq}, says that it is possible to find the final velocity of an object from its acceleration and the time that the object travels. How do you come up with a good math IA?. promotional emails that we send to you. This may indicate the start of a pattern. What is a mathematical model? 31) Grahams Number a number so big that thinking about it could literally collapse your brain into a black hole. 11 Math and computing. So there we have it, a well organized exploration of the idea and IB layout of your Mathematics IA! << /Length 5 0 R /Filter /FlateDecode >> Browse thousands of Internal Assessment, Extended Essay, and TOK examples. Optimizing areas: Optimizing the area of a rectangle is easy, but can you find a way to do it for any polygon? The examiner will be looking at the quality of the idea and the body of work in relation to the assessment criteria. Equation 4: y=sin2x. A first inversion chord starting on A will actually be in the key of F major. 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. Use Figure 2 and help the poor agent pick which house has a basement that will work. Many IB students find it hard to study mathematical concepts. 14) Methods for solving differential equations Differential equations are amazingly powerful at modelling real life from population growth to to pendulum motion. What if the client wanted the basement to have a width of 55 ft and be at least 1750 square feet? For more info on how to write the exploration, check out our completeMath IA Guide. 47) Hollow cubes and hypercubes investigation. These waves look very similar to the major chord waves, as only one note has changed; the C# has gone down by a semitone. According to student reviews, IB Maths is a struggle for many students working towards getting their diplomas. The table below shows more information about the notes in this chord. 26) Plotting the Mandelbrot Set using Geogebra to graphically generate the Mandelbrot Set. 43) Narcissistic Numbers what makes a number narcissistic and how can we find them all? 10 Topology and networks. Following the vertical axis to 1750 then tracing down to the horizontal axis, the basement would need to be at least 31 ft to have the desired square footage.

With these Topics ensure that you are not heavily reliant on the Physics aspect; put more emphasis on Mathematics. I wanted to make the sound wave of this note equal to the sine wave, which meant making 220Hz equivalent to ( typing error). 1. This chord, however, has 3 notes, so it can be more easily compared to the other chords I have looked at. So this involves you writing down the mathematics on paper to see if your topic will work. These statistical analyses and plots model the input data and allow the researcher to understand different attributes of the data set. Math models have been around for centuries, and they can describe everything from moving objects to chemical formulas. Nonetheless, if you feel like you want to search for your topics, an excellent place to start would be the IB Mathematics textbook. This means, that perhaps in the future music can be created entirely mathematically. 33) Can you solve an Oxford entrance question?
