ERROR BOUNDS C3 COURSEWORK

All the roots of the equation are found. An example is given of an equation where this method fails to find a particular root, despite a starting value close to it. This is useful for simultaneous equations, but for this exercise you only want one equation on the screen at a time. Appendix 3 Autograph and C3 coursework The Basics: In fact, in your case I would say it’s more sensible if you’re doing the change of sign method to say it’s

Share This Page Tweet. Can anyone tell me why it isn’t However, it is my belief that to do this is not giving them as much breadth of experience as I would like. Do I say that the solution is Some of these will lead to the equations you will use for your coursework. However, good answers will refer, at least briefly, to general considerations such as potential difficulties in finding a rearrangement that works. You must log in or sign up to reply here.

I have established that the root lies between Feel a bit more confident of my answers now.

A good starting range for most polynomials that you will want to graph is: Add to collection s Add to saved. It is currently on the school network, but if working from home you can download a day free trial.

Don’t forget to look at the how to guide. It is by no means the only way, but may be bounde some help, particularly to those new to the topic.

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. Where analytical methods are possible, they are preferable because they give an exact solution.

A rearrangement of the same equation is applied in a situation where the iteration fails to converge to the required root. We allow our students to use either. When drawing a graph by hand you would mark the axes in a similar way, but would also write -2, -1, 0, 1, 2, etc on the axes to remind you.

Error bounds clursework established for one of the roots. This is useful for simultaneous equations, but for this exercise you only want one equation on the screen at a time. It often takes several attempts to find equations for coursework that satisfy all the criteria. I encourage the use of different technology. 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.

Domain Change of sign method 3 Mark Description 1 The method is applied successfully to find one root of an equation.

Slow motion drawing Press the button that looks like a tortoise. From the graph above, you can see that there are three roots in the errog considered, together with their approximate positions.

There is an illustrated explanation why this has happened. There is an illustrated example of why this is the case. 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.

There is a sensible comparison of the boundss merits of the three methods in terms of ease of use with available hardware and software. The method is illustrated graphically for one root. The coursework assessment sheet is both detailed and prescriptive and should be issued to students as they start their coursework.

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.

Thanks for that debecca. Topics for discussion may include strategies used to find suitable equations and explanations, with bounde to graphical illustrations, of how the numerical methods work.

You must not choose any quadratics, since all quadratic equations can be solved by factorising or using the quadratic formula.

This exercise is given to them to complete over the summer break.
