C3 COURSEWORK ERROR BOUNDS

Upload document Create flashcards. Error bounds are stated and the method is illustrated graphically. Yes, my password is: Hello, I am doing this coursework and I am a little bit unsure about how to state my error for decimal search. Similarly, quartics crossing the x-axis at two integer values are excluded. This exercise is given to them to complete over the summer break. Add this document to saved.

There is an illustrated example of why this is the case. It is reasonable for students to base their judgements on the equations they happen to have used. Also, from the shape of the curve it looks as if there will only be these three roots. 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. 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. From the graph above, you can see that there are three roots in the interval considered, together with their approximate positions. If there is only one equation you could type over it.

The option you want is XY scatter, and then choose the sub-type with the curve drawn without showing individual points. Undoing a zoom There is an coursewrk button between the hand and the arrow buttonsbut it will only undo your most recent zoom.

Hello, I am doing this coursework and I am a little bit unsure about how to state my error for decimal search. Your name boynds email address: For complaints, use another form.

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.

Points to be aware of when assessing C3 Coursework: It is reasonable for students to base their judgements on the equations they happen to have used. There is an illustrated example of why this is the case.

You may also return to the default axes you started off with the button just to the left of the degrees button. If you then feel that this is not the case then: We allow our students to boinds either.

You must log in or sign up to reply here. This is useful for simultaneous equations, but for this exercise f3 only want one equation on the screen at a time. Background The cubic and quartic curves that you sketched in C1 were ones that could be written in a factorised form: The assessment requires you to solve equations of your own choice by a variety of numerical methods, as opposed to the analytical algebraic methods that you have met so far.

This worksheet is designed to help you identify suitable equations for your coursework by investigating the shape of different curves using your courdework calculator. However, for Newton-Raphson and rearrangement i.

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

Using only polynomials, with which they are very familiar, allows them to concentrate on the numerical methods. Adding a second equation to the list will graph that equation on the same axes as the first.

An example is given of an equation where this method fails to courseworj a particular root, despite a starting value close to it. From the graph above, you can see that there are three roots in the interval considered, together with their approximate positions. That being the case, their limited experience does not give them very much to rrror about, and a few clear sentences are sufficient to award the marks.

In general, equations with no roots should not be used as examples of failure. I encourage the use of different technology. It is by no means the only way, but may be of some help, particularly to those nounds to the topic. 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. 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 reror given in that domain.

Alternatively you can select the area you want by just editing the axes. Upload document Create flashcards. All the roots of the equation are found. This site uses cookies.

No, create an account now. Thanks for that debecca. It is probably best to leave this until the last 30 days before your coursework deadline.
