IGCSE Maths- Quick Revision 1

My quick overview of a few IGCSE maths topics. These are only a few and hopefully I will make more for the other topics soon.

Basically each page has some very brief info and a link to a good revision page or video for the topic.

If you have no idea about a topic there are two recommended websites on the contents page too...

Enjoy ... if you like revision :\

Quadratic Equations
If numbers (factors) multiplied together equal zero, then at
least one of the factors must equal zero. Using this fact we can
solve this type of equation.
You can recognise a quadratic equation because it will contain
a factor ("part or thing in the equation") that is squared!
There are a number of ways to solve them, hence there are a
few different types of question, all related to quadratic
equations...…read more

Here's a taster:

Areas of S ectors
To find the area of a sector you need to
know the equation for the area of a
circle... Pi x r^2 r=10
Or in words Pi times radius squared.
So the area of this circle is 314 cm^2
Types of Question
What is the area of a sector of 42
degrees?

Circle Theorem
There are too many rules to fit on this page.
Most of them are simple and you will probably
recognise them when they come up.
But be careful sometimes they are hidden
amongst many other lines and measurements.
The link below takes you to a very useful PDF
to help learn and remember the Rules of Circle

Irrational Numbers
Irrational numbers are numbers that can't be expressed as a fraction.
Basically these are recurring numbers, like Pi, that go on forever...
1.5 = 1 ½
2 = 2/1
2.2145640836040608597057840769.... = as a fraction ????
Types of Question
Rationalise
Simplify/ Reduction
Use common factors to reduce.

BLANK PAGE
Exam tips: at the end of your paper you may notice a
page marked: BLANK PAGE, as shown above. This is a

this challenging question.
Please read the exam tips
on this page,
They are very useful!
There are no more pages in the booklet...
except this one.
