The aims of this coursework are that students should appreciate the principles of numerical methods and at the same time be provided with useful equation solving techniques. Where analytical methods are possible, they are preferable because they give an exact solution. Start by familiarising yourself with the important menu options: The methods I will use are:. I think you have to give these to at least 5sf but check the coursework guide. That being the case, their limited experience does not give them very much to write about, and a few clear sentences are sufficient to award the marks.

There is an illustrated explanation why this has happened. In general, equations with no roots should not be used as examples of failure. Similarly, quartics crossing deciml x-axis at two integer values are excluded. Emphasize that it is not at all like GCSE coursework if they have done that since, in my experience, few of my students enjoyed that and were not confident about exactly what was required to achieve a high mark.

Ease of use comparing each method to each other when using Geogebra- citing any formulae meii may have used. The assessment requires you to solve equations of your own choice by a variety of numerical methods, as opposed to the analytical algebraic methods that you have met so far. The coursework assessment sheet is both detailed and prescriptive and should be issued to students as they start their coursework. There is a sensible comparison of courswwork relative merits of the three methods in terms of speed of convergence.

These numbers are not on the calculator axes, so it is best to choose a scale that you will remember easily.

Pressing it will give a display of all results found during the session. There is an illustrated example of why this is the case. However, it is my belief that to do this is not giving them as much breadth of experience as I would like.
