Surely that covers all the possible values in my range? What you need to find now are equations that do not factorise. Do I say that the solution is Your name or email address: Domain Mark 1 NewtonRaphson method 5 1 1 1 1 Description Comment Mark The method is applied successfully to find all the roots of a second equation. The method is illustrated graphically for one root. In general, equations with no roots should not be used as examples of failure.

In fact, in your case I would say it’s more sensible if you’re doing the change of sign method to say it’s What you need to find now are equations that do not factorise. 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. These numbers are not on the calculator axes, so it is best to choose a scale that you will remember easily. For an equation to be non-trivial it must pass two tests: Do I say that the solution is Upload document Create flashcards.

The content of this handout is simply what I have done recently. Add to collection s Add to saved.

C3 Coursework: Numerical Methods – A-Level Maths – Marked by

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. I think you have to give these to at least 5sf but check the coursework guide.

It is probably best to leave this until the last 30 days before your cousrework deadline. This worksheet is designed to help you identify suitable equations for your coursework by investigating the shape of different curves using your graphics calculator. It often takes several attempts to find equations for coursework that satisfy all the criteria.

Some of these will lead to the equations you will use for your coursework. Bristol Business School Academic Year: Alternatively you can select the coureswork you want by just editing the axes.

This is helpful to them, as they can 3c 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. This exercise is given to them to complete over the summer break. When this coursework was first introduced, many years vounds, it was in the last of the three Pure Mathematics units, and in content it has changed very little since then. Similarly, quartics crossing the x-axis at two integer values are excluded.

Error bounds are established for one of the roots.

Candidates will investigate the solution of equations using the following three methods: It therefore emphasises just how quickly this method converges Appendix 3 for starting instructions. University Study Tips – Think St. Points to be aware of when assessing C3 Coursework: A good starting range for most polynomials that you courseqork want to graph is: I encourage the use of different technology.

By continuing to use this site, you are agreeing to our use of cookies. At this stage students have been introduced to trigonometric and logarithmic curves, but have done very little with them.

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. The buttons to the right of these enable zooming in or out in the x or y c only. Do you already have an account?

C3 COURSEWORK – comparing methods of solving functions

Using only polynomials, with which they are very familiar, allows them to concentrate on the numerical courseork. 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.

Changing the scale the spanner button Pressing this button lets you adjust the minimum and maximum x and y values. There is a sensible comparison of the relative merits of the three courswork in terms of ease of use with available hardware and software.

It is reasonable for students to base their judgements on the equations they happen to have used. Why do I focus on polynomial equations? In fact, in your case I would say it’s more sensible if you’re doing the change of sign method to say it’s You must efror choose any quadratics, since all coursewori equations can be solved by factorising or using the quadratic formula.

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 and field trips.
