### ERROR BOUNDS C3 COURSEWORK

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. The buttons alongside this one allow for pausing etc. This automatically moves you to the next line. 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. 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. 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.

It is by no means the only way, but may be of some help, particularly to those new to the topic. 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. Some of these will lead to the equations you will use for your coursework. At this stage students have been introduced to trigonometric and logarithmic curves, but have done very little with them. Do you already have an account? 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. 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.

For the root in All curves are now drawn in slow motion.

Adding a second equation to the list will graph that equation on the same axes as the first. The buttons to the right of these enable zooming in or out in the x or y directions only. The scale that will be used is coursewor, you used for the previous graph, and may be totally unsuitable. Suggest us how to improve StudyLib For complaints, use another form.

Undoing a zoom There is an undo button between the hand and the arrow buttons eror, but it will only undo your most recent zoom. There is a sensible comparison of the relative merits of the three methods in terms of speed of convergence. To select a second curve, you must first hold down the SHIFT key on the keyboard, and then repeat the above.

This will be on the top line of the display. For several years I have used a different approach which proved very successful.

The coursework requirements are: Hello, I am doing this coursewok and I am a little bit unsure about how to state my error for decimal search. Error bounds are stated and the method is illustrated graphically. However, good answers will refer, at least briefly, to general considerations such as potential difficulties in finding a rearrangement that works. Can anyone tell me why it isn’t A rearrangement of the same equation is applied in a situation where the iteration fails to converge to the required root.

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.

Changing the scale the spanner button Pressing this button lets you adjust the minimum and maximum x and y values. They do need to make clear to the assessor what hardware and software they have used. You cougsework add this document to your study collection s Sign in Available only to authorized users. Consequently, they do decimal search as their change of sign method, using the graph and table facilities from their calculator.

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. Candidates will investigate the solution of equations using the following three methods: Where analytical methods are possible, they are preferable because they give an exact solution.

We allow our students to use either. Connect with like-minded professionals and have your say on the issues that matter to you.

Press EXE again to draw the graph. I encourage the use of different technology.

This exercise is given to them to complete over the summer break. Also, from the shape of the curve it looks as if there will only be these three roots.

Pressing it will give a display of all results found during errlr session. It is reasonable for students to base their judgements on the equations they happen to have used. Error bounds are established for one of the roots.
