This process can help you reflect on new relevant logic that you may not have known previously. Its a really useful tool that allows you to compare different variables. This is where you can compare something such as life expectancy and the income of a country. How many different ways can we use to solve a number theory problem? the Do not simply place these simply as appendices at the end of the essay - they should be fully and clearly labelled to ensure that the examiner knows what you've included and why. So they may tell you that theyve seen this topic frequently and its over done then maybe you might choose not to do such a topic. An equation writes the relationship between quantities, and a graph is a visual representation of that relationship. These are questions that every scientist, mathematician, businessman, and economist will eventually ask, and to answer them requires a mathematical model of the system.
