# MEI C3 COURSEWORK ERROR BOUNDS

The method is illustrated graphically for one root. Error bounds are stated and the method is illustrated graphically. Hello, I am doing this coursework and I am a little bit unsure about how to state my error for decimal search. There is an illustrated explanation why this has happened. 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. Appendix 3 Autograph and C3 coursework The Basics: 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.

Your coursework uses three methods and ideally you should choose equations where the associated graph is going to cross the x-axis 2 or 3 times. Start by familiarising yourself with the important menu options: The coursework assessment sheet is both detailed and prescriptive and should be issued to students as they start their coursework. Consequently, they do decimal search as their change of sign method, using the graph and table facilities from their calculator. It is currently on the school network, but if working from home you can download a day free trial. If there is only one equation you could type over it. Hello, I am doing this coursework and I am a little bit unsure about how to state my error for decimal search.

Consequently, they do decimal search as their change of sign method, using the graph and table facilities from their calculator. From the graph above, you can see that there are three roots in the interval considered, together with their approximate positions.

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. However, for Coursesork and rearrangement i. There is an illustrated explanation why this has happened. When drawing a graph by hand you would mark the axes in a similar way, but would also coirsework -2, -1, 0, 1, 2, etc on the axes to remind you.

Bristol Business School Academic Year: To set the ranges that you want on the axes, press Shift F3 VWindow and amend accordingly. That coudsework 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 scale that will be used is whatever you used for the previous graph, and may be totally unsuitable. A different equation must be used for each method. There is a sensible comparison of the relative merits of the three methods in terms of speed of convergence.

Changing the scale the spanner button Pressing this button lets you adjust the minimum and maximum x and y values. 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. However, it is my belief that to do this is not giving them as much breadth of experience as I would like. It often takes several attempts to find equations for coursework that satisfy all the criteria.

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.

In addition, you must not choose a cubic that crosses the x-axis at an integer value, since using the factor theorem you could then find a linear factor, reducing the cubic to linear times quadratic and therefore solvable.

Topics for discussion may include strategies used to find suitable equations mfi explanations, with reference to graphical illustrations, of how the numerical methods work. Can anyone courswork me why it isn’t You can add this document to your saved list Sign in Available only to authorized users.

For an equation to be non-trivial it must pass two tests: Similarly, quartics crossing the x-axis at two integer values are excluded. Val Hanrahan The coursework rationale is: This is useful for simultaneous equations, but for this exercise you only want one equation on the screen at a time.

This frequently led to less than satisfactory coursework, since they lost track of what they were supposed to be doing.
