Trimino Maths Coursework For this maths investigation, we had to investigate and patterns that we discovered involving the numbers used on a Truman and thereby deduce formulae to help us calculate unknowns. A trimino is similar to a domino yet has three side, as below. To begin with, I investigated the relationship between the highest number appearing on the trimino and the number of possible combinations. The table below shows the highest number o the trimino and the number of possible triminos. I began by taking the difference of the number of combinations, as shown above. As you can see, I had to take three differences before the differences were constant. This meant that the formula I wanted had to contain a cubic function. During my research prior to this investigation, I discovered the formula: ax3 + bx2 + cx + d = y I believed I could use this formula to help me...
