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. B. 8) Squaring the circle: This is a puzzle from ancient times which was to find out whether a square could be created that had the same area as a given circle. So an advantage of choosing such a topic is you can do the investigation at home. 7) Patterns in Pascals triangle: There are a large number of patterns to discover including the Fibonacci sequence. A mathematical model is commonly written as an equation. 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. By doing this, you can determine findings throughout the process. The gaps in the ratios do not directly relate to the difference in semitones, as the semitones do not have equal frequencies-the frequencies of semitones diverge as the frequencies increase, and the notes get higher in pitch. 9) Designing bridges Mathematics is essential for engineers such as bridge builders investigate how to design structures that carry weight without collapse. You need to know what will be in the y-axis and what will be in the x axis so this can be something like a velocity time graph.

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. You can watch a short video on it here. It is about evaluating the research to pick up on all evidence that goes beyond what a typical mathematical test would. For example, the common chemical formula for water, {eq}H_20 {/eq}, means that there are two hydrogen atoms for every one oxygen atom in a molecule of water. Modeling of any kind as it also takes a lot of effort. The challenge is to see how many different shapes can be made with a given number of squares and how can they fit together?

So lets say you decide to assess Lewis Hamiltons speed at a certain velocity of a given time. 1. How long will our forests last? Models for the height of water in a cylindrical container, Advice from an IB Examiner on topics you should avoid, Differential Equations-the use of differential equations to model things in engineering or physics (ensure you do not talk much about the science. With 2 candidates this is logical, but what if they have more than 2? 7) Quantum Mechanics a statistical universe? 31) The Shoelace Algorithm to find areas of polygons. There are many different types of graphs, and graphs are commonly used mathematical models for data analysis because it is possible to visualize a system without knowing how all of the pieces fit together. Maths is closely connected with astronomy see how we can work out the distance to the stars. Topics that rely more on natural sciences such as physics and put less emphasis on Math. Terms like plug in or put in should be replaced with mathematically sophisticated words like substitute.. This is a puzzle that was posed over 1500 years ago by a Chinese mathematician. In this mathematical exploration, the students attempts to study the mathematical relationship of notes within chords inn harmony and discordant chords. Erroneous notation, it should be 554.37x/440). No mathematical explaination on how these are determined) ( B. I will now look at the augmented 6th, another discordant chord. This chord, like the first inversion, is another different rearrangement of the notes in a major chord. How can we use computers to gain a deeper understanding of sequences? 32) RSA code the most important code in the world? 2) Goldbachs conjecture: Every even number greater than 2 can be expressed as the sum of two primes.

What would projectile motion look like on different planets? 51) Complex numbers as matrices Eulers identity. During the reflective stage, connect the results with the initial aims. For example, physicists studying proton-proton collisions at CERN use computer modeling to learn about the particles produced during the collisions. Financial Mathematics Equations & Problems | What is Financial Mathematics? Get unlimited access to over 84,000 lessons. The kinematic equations can be used to describe the motion of any moving object, and because they relate different quantities present in a single system to describe another aspect of the system, the kinematic equations are considered a mathematical model. Furthermore the musical chords are representated with the help of multiple sinosodial curves, so that they can be broken down and their mathematical relation can be understood. 3) Stacking cannonballs solving maths with code how to stack cannonballs in different configurations. This is an nice example of how you can investigation optimization of the area of different polygons. Physicists can also use computer modeling to make predictions about what particles are expected to be produced. The average total flow of pedestrians and cars is then given by: If we take (for example) a = , b = 10, T = 1 then a plot of F as a function of D is given below: 14) Galileos Inclined Planes. 8) Log Graphs to Plot Planetary Patterns.
