From the graph above, you can see that there are three roots in the interval considered, together with their approximate positions. The buttons alongside this one allow for pausing etc. There are many other facilities, but if you are familiar with all the above, you will be in a position to add graphs to your coursework. The coursework requirements are: I think you have to give these to at least 5sf but check the coursework guide. Instructions refer to the Casio fx, but similar operations apply to other models. They do need to make clear to the assessor what hardware and software they have used.
Error bounds are established for one of the roots. Hello, I am doing this coursework and I am a little bit unsure about how to state my error for decimal search. For complaints, use another form. If there is only one equation you could type over it. Selecting a curve Positioning the mouse alongside a curve until a black arrow appears and then left-clicking the mouse turns the curve black and selects it for analysis. Domain Comparison of methods 3 Mark Description 1 One of the equations used above is selected and the other two methods are applied successfully to find the same root.

boynds Your solution bounds are 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.
The buttons to the right of these enable zooming in or out in the x or ereor directions only. It is not sufficient to do a general illustration. 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. Too frequently, however, students feel obliged to pad these out with a load of waffle! Exercise For each of the graphs in the list, use the range suggested above to draw the courseworj on your calculator and then copy the graph onto file paper, not graph paper adding the scale to the axes.
Suggest us how to improve StudyLib For complaints, use another form.
The option you want is XY scatter, and then choose the sub-type with the curve drawn without showing individual points. For complaints, use another form.
I have established that the root lies between 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.
To select a second curve, you must first hold down the SHIFT key on the keyboard, and then repeat the above.

C3 COURSEWORK – comparing methods of solving functions
Domain Comparison of methods 3 Mark Description 1 One of the equations used above is selected and the other two methods are applied boynds to find the same root. There is a sensible comparison of the relative merits of the three methods in terms of ease of use with available hardware and software. You will be very lucky if the first five functions you think of are all suitable.
C3 COURSEWORK – comparing methods of solving functions – A-Level Maths – Marked by
Using only polynomials, with which they are very familiar, allows them to concentrate on the numerical methods. At this stage students have been introduced to trigonometric and logarithmic curves, but have done very little coursweork them. Continue by pressing ‘Next’ until you are ready to ‘Finish’ This gives you the shape of the curve, but is not as good as ‘Autograph’ for the detail you need to include with the coursework.
Although this apparently does everything for them I require students to do the first iteration manually, which means that a polynomial equation must ertor used. Domain Change of sign method 3 Mark Description 1 The method is applied successfully to find one root of an equation.
