My Maths Formula that no one belives that it was posible to make for our coursework
In our GCSE maths, the corsework was about a magic E. We had to answer two questions and then extented it. In the extention I desided to make up a gerneral formula for any shape on any size grid. The gid counted up. The people who did it will understand. The general formula begins below. the general formula is written in brief.

There are 3 things you need to know before you can use it.
1 The value of the x or the lenght of the x axis.
2 The top left hand corner of shape this can be used to find out how many squares down and in the shape is on the grid (not explain how to.)
3 The size and shape of shape.


a+bx+c

a=the number of squares in the shape.

b=each line down another x is added for each square in the shape on that line. Line one has no x's.
so d=line number -1 because of the first line haveing no x's
h=number of squares in that line
So multiply them together (dxh) this needs to be done for each line in the shape. Then add them all together to find b.

c=It is an arithmetic progression using the formula 1/2n(a+b) but this will not quike work. The first collunm has no value because of in the formula it is used twice in the brackets there needs to be a -2 also. Also the letters need changing.
n to h it has the same meaning as before, the number of squares in that line
a to f
f=the number of quares in the most left square of shape in that line.

b to g
g=the number of squares in the most right square of shape in that line.

1/2h(f+g-2)
This needs to be done for each line then added together to give c.

x=the range of the x-axis of the grid +1




Other things you might need to know


E=MC2 The formula for everything. E=energy that is = to the Mass x the Speed of light squared. This means you can have a very small mass but still a large amount of energy as the speed of light is so fast.

Speed of light in a vacuum: 299792458ms-1 (m/s) or just 3x10 to the power of 8 ms-1 (m/s) (300000000ms-1)the symbol is c

Acceleration of free fall: 9.80665 ms-2. the symbol is g

Absolute zero is the coldest anything can be. but it can not be reached as the third law of thermodyamics states. Absolute zero is of temperature -273.15 c or 0 kelvin. (Depends on where you look as some places gives it as -273.16 = 0 K.)

Laws of thermodynamics
1 energy can be neither created nor destroyed.
2 it is impossible for an unaided self-acting machine to covey heat from one body to another at a higher temperature.
3 it is impossible by any procedure, no matter how idealized, to reduce any system to the absolute zero of temperature (0 K / -273.15 c / -459 F) in a finite number of operations.

Pi = 3.1415926535897932384626433832795 to 31 decimal places

A gigabyte is 1073741824 bytes
A megabyte is 1048576 bytes
A kilobyte is 1024 bytes
A byte is 8 bits

It is like that because computers work in powers of 2 as they work on binary of 1's and 0's.

I have found a good way to change decimal numbers to binary. If you put your computer calcultor in to sinentifc mode you can change it between dec and bin the largest binarry number can only be 32 bits long as the computers only have 32 bit processors.
