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 :\

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

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.

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

BLANK PAGE

Exam tips: at the end of your paper you may notice a
page marked: BLANK PAGE, as shown above. This is a
trick question,as the page is not actually blank.

Unfortunately most exam boards only give [0] marks for
this challenging question.
