ERROR BOUNDS C3 COURSEWORK

That being the case, their limited experience does not give them very much to write about, and a few clear sentences are sufficient to award the marks. Thanks for that Calum. Error bounds are established for one of the roots. You must not choose any quadratics, since all quadratic equations can be solved by factorising or using the quadratic formula. I have established that the root lies between Bristol Business School Academic Year:

They do need to make clear to the assessor what hardware and software they have used. Press EXE to store it. There is a sensible comparison of the relative merits of the three methods in terms of ease of use with available hardware and software. Half marks may be awarded, but the overall total must be an integer so the assessor must make the decision to round up or down. One way of identifying 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 frequently led to less than satisfactory coursework, since they lost track of what they were supposed to be doing.

Add this bouns to collection s. Alternatively you can select the area you want by just editing the axes. Press EXE at the end to return to the equation.

Undoing a zoom There is an undo button between the hand and the arrow buttonsbut it will only undo your most recent zoom. Why do I focus on polynomial equations? I think you have to give these to at least 5sf but check boynds coursework guide. There is an illustrated example of why this is the case. A different equation must be used for each method. 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.

Add to collection s Add to saved. When this coursework was first introduced, many years ago, it was in the last of the bounnds Pure Mathematics units, and in content it has changed very little since then. Appendix 3 Autograph and C3 coursework The Basics: Candidates will investigate the solution of equations using the following three methods: Points to be aware of when assessing C3 Coursework: Thanks in advance for any help, BF.

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

One way of identifying cubic and higher order equations that do not have an analytical solution bounrs to look for associated graphs that cross the x-axis at non-rational values.

It is currently on the school network, coureework if working from home you can download a day free trial. 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. An example is given of an equation where one of the roots cannot be found by the chosen method.

To select a second curve, you must first hold down the SHIFT key on the keyboard, and then repeat the above. Exercise For each of the graphs in the list, use bunds 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. Feel a bit more confident of my answers now.

A good starting range for most polynomials that you will want to graph is: All the roots of the equation bounde found. Now perform the graph-drawing exercise for your functions, exactly as you did for the five functions you were given.

University Study Tips – Think St. You may also return to the default axes you started off with the button just to the left of the degrees button.

Do you already have an account? They do need to make clear to the assessor what hardware and software they have used.

In each case, decide if those values of x and y give appropriate detail to the part of the curve where it crosses the x axis. These numbers are not on the calculator axes, so it is best to choose a scale that you will remember easily. That being the case, their limited experience does not give them very much to write about, and a few clear sentences are sufficient to award the marks. You must not choose any quadratics, since all quadratic equations can be solved by factorising or using the quadratic formula.

Topics for discussion may include strategies used to find suitable equations and explanations, with reference to graphical illustrations, of how the numerical methods work.
