Personalised Revision Tool for

Edexcel C3

Aims

This Revision Tool aims to make your revision smarter and more effective. It aims

to:-

Identify gaps in your understanding and knowledge.

Give a short summary & example for each sub-topic.

Provide hyperlinks to MyMaths lessons for most sub-topics.

Using the short tests

There are 2 mini-assessments for each sub-topic.

Use the first test to identify which topics you need to work on. If you get a good

mark you will not need to use the second test on this topic.

Use the second test to measure the level of improvement after remedial work has

been undertaken.

This PRT is not a substitute for, or an alternate to, doing past papers.

A programme of completing whole past papers is essential for success.

Change of Sign Methods

To find the root of a function f(x), if

f(a) > 0

f(b) < 0

and the function is continuous, then there is a root between a and b.

We can narrow this down by successively halving the size of the interval, until we get an answer to the

required accuracy.

Example

We can continue this method indefinitely, to whatever accuracy we require

This method is useful for confirming the existence of a root between two given values. It

can be unreliable however, sometimes failing to find a root(s) when they are very close

together, or ‘finding’ a root that doesn’t exist.

Iterative Methods

(there are many other re-arrangements you could have done)

Then start at any value (it will be given in the question; here we use x=0, and show 3

iterations)

This method continues until it converges on the solution x = 0.276 (to 3 dp)

Iterative methods will often fail to find the root for given re-arrangements. If this is the

case, you must try a different re-arrangement.
