T- TOTAL In this test I will be finding out the equation of the t- total and the formula of different grid sizes like 10 by 10,11 by 11 and 12 by 12.The investigation has the aim to find the pattern between the t- total and the grid size. I have drawn several t- shapes in the grid below and worked out the t- total for them I have also put the results in a table shown below 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 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 T- number t-total 20 37 21 42 22 47 23 52 24 57 25 62 The relationship between the t- totals is 5.Now the algebra Point Of View Tn= (n-19)+(n-18)+(n-17)+(n-9)+n Tn = 5n -63 this is for a 9 by 9 grid. Does this agree with the table's equation? T20 = 5 x 20 - 63 100 - 63 = 37 let me make sure that this does work by doing two more tests T21 = 5 x 21 = 105 - 63 = 42 and...
