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 is probably best to leave this until the last 30 days before your coursework deadline. Can anyone tell me why it isn’t We allow our students to use either. 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.

I have established that the root lies between Right-clicking the mouse This operation gives several additional menu options, especially once one or more curves have been selected. The content of this handout is simply what I have done recently. Display of results The results box is situated to the left of the spanner button. Val Hanrahan The coursework rationale is: An example is given of an equation where one of the roots cannot be found by the chosen method.

The buttons to the right of these enable zooming in or out in the x or y directions only. If there is only one equation you could type over it. Or can I say that it is This will be on the top line of the display.

Rationale The aims of the coursework are that students should learn how differential equations are used to solve C3 and.

Surely that covers all the possible values in my range? This is helpful to them, as they can check 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.

Alternatively you can select serch area you want by just dcimal the axes. MEI C3 coursework – numerical mei ocr c3 coursework mark scheme. There is a sensible comparison of the relative merits of the three methods in terms of speed of convergence.

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 undo button between the hand and the arrow buttonsbut it will only undo your most recent zoom.

If you then feel that this is not the case then: 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.

Press EXE at the end to return to the equation.

In addition, you must not choose a cubic that crosses the x-axis at an integer value, since using the factor theorem you could then find a linear factor, reducing the cubic to linear times quadratic and therefore solvable. The assessment requires you to solve equations searcy your own choice by a variety of numerical methods, as opposed to the analytical algebraic methods that you have met so far. 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 Changing the scale the spanner button Pressing this button lets you adjust the minimum and mi x seagch y values.
