To prove these results algebraic equations can be used. When the value of X is replaced by a number the difference will always be 10. x x+1 x+10 x+11 Expression 1 x(x+11)= x2 +11x Expression 2 (x+10) (x+11) = x2 +10x+x+10 = x2 +11x+10 x2 +11x+10 - x2 +11x = 10 3x3 squares 2 3 4 12 13 14 22 23 24

4. ## T-Total. In order to find the relationship between the T-number and the T-total I need to show the numbers in the T algebraically

74 75 77 78 79 80 81 82 In order to find the relationship between the T-number and the T-total I need to show the numbers in the T algebraically as shown in the diagram below. N-19 N-18 N-17 N-9 N This is worked out with the grid size because how you get one square up is by taking 9 because it is a 9*9 grid. If I move left I +1 and if you move right you -1. If I add all the numbers together in the diagram above you get 63 and that is the same wherever the T is on a 9*9 grid.

5. ## ICT Coursework: Data Management Systems

The advantages of using an ICT solution are that a lot of space is saved (there is no need for lots of loose paper), time is saved (all calculations are done automatically), and the business is much easier to manage. For example, income and expenditure can be easily viewed, and stock is easily managed with the remaining stock kept in the spreadsheet. Also, all data about the business can be accessed easily, and almost anywhere. By backing up to a disk, the spreadsheet can then be viewed from any computer that has a disk drive, and the appropriate software.

9. ## T -Totals. From this 9*9 grid I will collect a number of T Shapes with T Numbers after collecting these I will put them into a table and will investigate to find any relationship between them.

10. ## T-Shapes Coursework

I have chosen my three T-shapes and have labelled the T-Numbers in them appropriately. I am now going to work out the T-Totals for each of my T-shape. T-number-20=20+11+1+2+3=37 T-number-21=21+12+2+3+4=42 T-number-22=22+13+3+4+5=47 T-Number T-Total T-number-20 20+11+1+2+3=37 T-number-21 21+12+2+3+4=42 T-number-22 22+13+3+4+5=47 From looking at the table above a clear pattern can be seen that as the T-number increases the T-total also increases by 5. This is because there is five numbers in a T-shape. The ratio then for the T-total is for every T-number increase by 1 the T-total increases by 5. A ratio of 1:5.

11. ## Black and white squares

Formula = 4+N I am going to test this formula with an example. Sequence number = 56 Consistent difference = 4 The number of white squares = 4+56= 60 The black squares I would have take in to thought, that the black squares of a pattern equal the total number of squares in the previous pattern, this helps in the search of a formula. We also know that the difference between the black squares and the total of all the squares is 4.

61 62 63 71 80 80-61=19 80-62=18 80-63=17 80-71=9 Since my results have been proven correctly, I will now work out a formula for any T-Shape on a 9x9 grid. If I give my T-Number a letter (n) to represent it, the formula will be: 1 2 3 11 11 20 n-19 n-18 n-17 n-9 n = *THIS FORMULA APPLIES ON ANY T-SHAPE ON A 9x9 GRID ONLY.* After this, I decided to work out another formula for the T-Shape.

16. ## T-Totals. Firstly I am going to do a table of 5 x 5 and look at the T-totals and T-numbers.

15 + 24 = 57 T-total = 57 The T-number is 25 6 + 7 + 8 + 16 + 25 = 62 T-total = 50 The T-number is 26 7 + 8 + 9 + 17 + 26 = 67 T-total = 67 The rest of the answers will be put into a table.

17. ## Maths Coursework on T-Shapes

In this investigation I will first find a formula to find the T-total using the T-number in a 9x9 grid, I will then use differing grid sizes to see what an affect this has on the formula. Then using this information I will find a formula, which will be true to all grid sizes. Then I will experiment with rotations and reflections on differing grid sizes to see what an affect it has on the formula. Then a Conclusion about T-shapes.

19. ## 1) Investigate the relationship between the T-total and the T-number. 2) Use grid of different sizes. Translate the T-shape to different position. Investigate relationships between the T-total, the T-numbers and the grid size.

T-number 20 21 22 23 24 25 26 T-total 37 42 47 52 57 62 67 This table clearly shows that the numbers go up by 5 every time the T-number goes up by 1. Now I can use trial and error to try to find the formula, I will then test what I believe to be the correct formula to see if it is. Because there is a difference of 5 between the T-totals I think that it is a logical place to start the formula.

20. ## Maths Coursework- Borders

I will be working systematically in my investigation because if I work in a particular order it will be easier for to see a pattern and links in the sequences. Finally I will be looking at different ways of getting the formulae and also extending my investigation into 3 dimensions.

23. ## See how many squares would be needed in order to construct any cross-built up in the way described in the investigation.

For the next pattern I predict the total number of squares would be 41. I am now going to check if my prediction is correct, using the pattern 1+3+5+7+9+7+5+3+1=41. I was right; this could be useful fact in searching for a formula. By gaining this information I will now draw a table of results and write down more patterns, as the moment I have is not conclusive. I have also noticed that to find the number of shaded squares in the next pattern, you have to use the total number of squares from the previous pattern.

24. ## T-Totals. Aim: To find the relationship between the T-Total and the T-number. To find a formula that works for every grid size. To find how rotating the T-shape effects the T-Total To find a formula that works f

I will use the second method to succeed in finding the Constant. T-total 1=37 37=(5*20)+C C=37-5*20 C=37-100 C= -63 T-number=20 Therefore T=5n-63 I will try this formula on T-Number 50: Using my formula, T-number=69 so T=(5*69)-63 =345-63 =282 Now I need to show it is correct: T=50+51+52+60+69 =282 My prediction was correct so my formula is right. This is my first aim. I will now use Grid size 8 to see if there is any difference in the formula I have found for Grid size 9 and if there is to work out the connection between the Grid size and the formula.

25. ## Investigating the relationship between the T-totals and the T-number.

So in this case the ratio between the T-number and the T-total is 1:5. This can help me because when I want to translate a T-shape that is in another position. For instance when I the T-shape here. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62
