For an equation to be non-trivial it must pass two tests: 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. Some of these will lead to the equations you will use for your coursework. They feel comfortable with polynomial graphs, having sketched them without calculators in C1, and are able to differentiate polynomial functions for those methods that require this. I think you have to give these to at least 5sf but check the coursework guide. A good starting range for most polynomials that you will want to graph is: Repeated failure in this respect should incur some overall penalty, probably 1 2 a mark.

We allow our students to use either. 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. 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. It is not sufficient to do a general illustration. Topics for discussion may include strategies used to find suitable equations and explanations, with reference to graphical illustrations, of how the numerical methods work. It often takes several attempts to find equations for coursework that satisfy all the criteria.

Any list provided should be sent with the scripts to the external moderator. Start by familiarising yourself with the important menu options: Adding a second equation to the list will graph that equation on the same axes as the first.

Press EXE again to draw the graph. Instructions refer to the Casio fx, but similar operations apply to other models.

To set the ranges that you want on the axes, courseworrk Shift F3 VWindow and amend accordingly. Feel a bit more confident of my answers now.

We allow our students to use either. There is an illustrated explanation why this has happened. I have established that the root lies between This will be on the top line of the display.

This exercise is given to them to complete over the summer break. One way of cuorsework cubic and higher order equations that do not have an analytical solution is to look for associated graphs that cross the x-axis at non-rational values.

This is useful for simultaneous equations, but for this exercise you only want one equation on the screen at a time.

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.

## C3 Coursework: Numerical Methods

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. Discussion in ‘ Mathematics ‘ started by bonusfeatureNov 25, Background The cubic and quartic curves that you sketched in C1 were ones that could be written in a factorised form: What you need to find now are equations that do not factorise.

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

Error bounds are stated and the method is illustrated graphically. Topics for discussion may include strategies used to find suitable equations and explanations, with reference to graphical illustrations, of how the numerical methods work.
