Yes, my password is: Do you already have an account? Adding a second equation to the list will graph that equation on the same axes as the first. Domain Comparison of methods 3 Mark Description 1 One of the equations used above is selected and the other two methods are applied successfully to find the same root. Press EXE to store it. They do need to make clear to the assessor what hardware and software they have used.

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. This automatically moves you to the next line. Yes, my password is: This is helpful to them, as they can check that everything is included; to you, as you can see where they think it is, if it is not immediately apparent; and also to the moderator. However, it is my belief that to do this is not giving them as much breadth of experience as I would like. The buttons to the right of these enable zooming in or out in the x or y directions only. Why do I focus on polynomial equations?

It is by no means the only way, but may be of some courswork, particularly to those new to the topic. You will be very lucky if the first five functions you think of are all suitable. Appendix 3 Autograph and C3 coursework The Basics: It is currently on the school network, but if working from home you can download a day error trial. It is reasonable for students to base their judgements on the equations they happen to have used.

## C3 coursework…..error bounds??

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. The buttons to the right of these enable zooming in or out in the x coursewrk y directions only. Add this document to saved. The content of this handout is simply what I have done recently. Continue by pressing ‘Next’ until you are ready to ‘Finish’ This gives you the shape of the curve, but is not as good as ‘Autograph’ for the ciursework you need to include with the coursework.

Hmm I’ve written an essay, can you tell I’ve been marking 20 of these this week? There is a sensible comparison of the relative merits of the three methods in terms of speed of convergence.

The scale that will be used is whatever you cougsework for the previous graph, and may be totally unsuitable. Start by familiarising yourself with the important menu options: Selecting a curve Positioning the mouse alongside a curve until a black arrow appears and then left-clicking the mouse turns the curve black and selects it for analysis.

# C3 Coursework: Numerical Methods – A-Level Maths – Marked by

An interview is also an ideal opportunity to pursue further any areas where there are errors or omissions in the coursework, although this will not affect the mark given in that domain.

Press EXE at the end to return to the equation. In each case, decide if those values of x and y give appropriate detail to the part of the curve where it crosses the x axis. An example is given of an equation where this method fails to find a particular root, despite a starting value close to it.

If you then feel that this bohnds not the case then: Why do I focus on polynomial equations? An example is given of an equation where one of the roots cannot be found by the chosen method. Add this document to collection s.

This means that either there is no root using that starting point, or the method converges to a different root from the one that was being sought. The coursework requirements are: When this coursework was first introduced, many years ago, it was in the last of the three Pure Mathematics units, and in content it has changed very little since then.

Exercise For each of the graphs in the list, use the range suggested above to draw the graph on your calculator and then copy the graph onto file paper, not graph paper adding the scale to the axes.

There are many other facilities, but if you are familiar with all bounda above, you will be in a position to add graphs to your coursework. Val Hanrahan The coursework rationale is: By continuing to use this site, you are agreeing to our use of cookies.

We allow our students to use either. For the root in Also, from the shape of the curve it looks as if there will only be these three roots. Error bounds are stated and the method is illustrated graphically.

University Study Tips – Think St. Slow motion drawing Press the button that looks like a tortoise. Pressing it will give a display of all results found during the session.
