C3 COURSEWORK ERROR BOUNDS

The coursework requirements are: 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. To set the ranges that you want on the axes, press Shift F3 VWindow and amend accordingly. Now perform the graph-drawing exercise for your functions, exactly as you did for the five functions you were given. Background The cubic and quartic curves that you sketched in C1 were ones that could be written in a factorised form: Display of results The results box is situated to the left of the spanner button.

My intention here is to pass on my thoughts on how this coursework can be done. Your e-mail Input it if you want to receive answer. Repeated failure in this respect should incur some overall penalty, probably 1 2 a mark. This will be on the top line of the display. An example is given of an equation where one of the roots cannot be found by the chosen method. For an equation to be non-trivial it must pass two tests: You can add this document to your saved list Sign in Available only to authorized users.

All the roots of the equation are found. At this stage students have been introduced to trigonometric and logarithmic curves, but have done very little with them. If you then feel that this is not the case then: A good starting range for most polynomials that you will want to graph is: It is not sufficient to do a general illustration.

Right-clicking the mouse This operation gives several additional menu options, especially once one or more curves have been selected. It often takes several attempts to find equations for coursework that satisfy all the criteria. Domain Change of sign method 3 Mark Description 1 The method is applied successfully to find one root of an equation.

The scale that will be used is whatever you used for the previous graph, and may be totally unsuitable. This means bonds either there is no root using that starting point, or the method converges to a different root from the one that was coursswork sought. Error bounds are established for one of the roots. Display of results The results box is situated to the left of the spanner button.

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. I encourage the use of different technology. Val Hanrahan The coursework boumds is: Or can I say that it is Centres may provide students with a list of at least ten equations from which they can, if they wish, coursewodk those they are going to use, but any list must be d3 to the moderator with the sample and changed for each examination session.

However, good answers will refer, at least briefly, to general considerations such as potential difficulties in finding a rearrangement that works. You can add this document to your study collection s Sign in Available only to authorized users.

Half marks may be awarded, but the overall total must be an integer so the assessor must make the decision to round up or down.

What you need to errro now are equations that do not factorise. To set the ranges that you want on the axes, press Shift F3 VWindow and amend accordingly.

C3 coursework…..error bounds??

My intention here is to pass on my thoughts on how this courseaork can be done. There is a sensible comparison of the relative merits of the three methods in terms of speed of convergence.

Some of these will lead to the equations you will use for your coursework. However, for Newton-Raphson and rearrangement i. Press EXE again to draw the graph.

You must not choose any quadratics, since all quadratic equations can be solved by factorising or using the quadratic formula. Your e-mail Input it if you want to receive answer. Thanks for that debecca.
