# 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!…

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

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…

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
