Any list provided should be sent with the scripts to the external moderator. Press EXE at the end to return to the equation. Centres may provide students with a list of at least ten equations from which they can, if they wish, select those they are going to use, but any list must be forwarded to the moderator with the sample and changed for each examination session. Thanks in advance for any help, BF. Your e-mail Input it if you want to receive answer.

The scale that will be used is whatever you used for the previous graph, and may be totally unsuitable. Why do I focus on polynomial equations?

Yes, my password is: Topics for discussion may include strategies used to find suitable equations and explanations, with reference to graphical illustrations, of how the numerical methods work. 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.

This will be on the top line of the display. Error bounds are stated and the method is illustrated graphically. Candidates will investigate the solution of equations using the following three methods: You can add this document to your study collection s Error in Available only to authorized users.

There is an illustrated example of why this is the case. The option you want is XY scatter, and then choose the sub-type with f3 curve drawn without showing individual points. Add to collection s Add to saved. To select a second curve, you must first hold down the SHIFT key on the keyboard, and then repeat the above.

The buttons to the right of these enable zooming in or out in the x or errror directions only. Do you already have an account?

# MEI C3 COURSEWORK STRUCTURED MATHEMATICS

We allow our students to use either. You must not choose any quadratics, since all quadratic equations can be solved by factorising buonds using the quadratic formula. For an equation to be non-trivial it must pass two tests: Although this apparently does everything for them I require students to do the first iteration manually, which means that a polynomial equation must be used.

This automatically moves you to the next line. The coursework assessment sheet is both detailed and prescriptive and should be issued to students as they start their coursework.

There is bounda illustrated explanation why this has happened.

## C3 COURSEWORK – comparing methods of solving functions

It is currently on the school network, but if working from home you can download a day free trial. Autograph is an advanced graph drawing package that will make the graphical side of the C3 coursework much simpler than drawing by hand or using Excel.

Consequently, they do decimal search as their change of sign method, using the graph and table facilities from their calculator.

What you need to find now are equations that do not factorise. Share This Page Tweet.

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 detail you need to include with the coursework. An example is given of an equation where one of the roots cannot be found by the chosen method.

## C3 Coursework: Numerical Methods

The assessment sheet should be issued at the start, and students should be made aware of how prescriptive the mark allocation is. Using only polynomials, with which they are very familiar, allows them to concentrate on the numerical methods.

You will be very lucky if the first five functions you think of are all suitable.

Slow motion drawing Press the button that looks like a tortoise. Start by familiarising yourself with the important menu options: Centres may provide students with a list of at least ten equations from which they can, if they wish, select those they are going to use, but any list must be forwarded to the moderator with the sample and changed for each examination session.

Srror you can select the area you want by just editing the axes. Points to be aware of when assessing C3 Coursework: Press EXE again to draw the graph.
