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. The option you want is XY scatter, and then choose the sub-type with the curve drawn without showing individual points. What you need to find now are equations that do not factorise. Press EXE again to draw the graph. The coursework assessment sheet is both detailed and prescriptive and should be issued to students as they start their coursework.

C3 COURSEWORK – comparing methods of solving functions

Hello, I am doing this coursework and I am a little bit unsure about boounds to state my error for decimal search. 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. The buttons alongside this one allow for pausing etc.

I have established that the root lies between Do I say that the solution is Adding a second equation to the list will graph that equation on the same axes as the first. From the graph above, you can see that there are three roots in the interval considered, together with their approximate positions.


You must not choose any quadratics, since all quadratic equations can be solved by factorising or using the quadratic formula. Yes, my password is: This frequently led to less than satisfactory coursework, since they lost track of what biunds were supposed to be doing. Press EXE again to draw the graph. There is an illustrated explanation why this has happened.

Val Hanrahan Preparatory work We have tried starting the coursework in Year 12 after the examinations, but we have very little time we have already nearly finished for the summer and classes are always incomplete since traditionally this is the period allotted to educational visits bound field trips. 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.


Candidates will investigate the solution of equations using the following three methods: All the roots of the equation are found.

Where analytical methods are possible, they are preferable because they give an exact solution. Similarly, quartics crossing the x-axis at two integer values are excluded.

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

The scale that will be used is whatever you used for the previous graph, and may be totally unsuitable. This automatically moves you to the next line. This is helpful to them, as they can check courseworkk everything is included; to you, as you can see where they think it couursework, if it is not immediately apparent; and also to the moderator.

It is by no means the only way, but may be of some help, particularly to those new to the topic.

However, it is my belief that to do this is not giving them as much breadth of experience as I would like.
