The objective of this coursework is to find the formula that gives the maximum product of any given number when split into parts.
For the first part of the coursework I am going to investigate the splitting of a number into two parts, then three parts and four Parts. For each number of parts, This will result with a formula that gives the maximum product.
PAIRS WHICH TOTAL 12 & PRODUCT OF THE PAIR
12,0 = 0 11,1 = 11 10,2 = 20 9,3 = 27 8,4 = 32 7,5 = 35 6,6 = 36 5,7 = 35 4" = 32 3,9 = 27 10 = 20 1,11 = 11 0,12 = 0
I will assume my maxi product is in the range between 7,5 and 5,7 because this where the product is at it¡¯s highest. So, 6.9 ¡¿ 5.1=35.19, 5.9 ¡¿ 6.1=35.99 Neither of these are higher than 36. So for my starting number 12, I have used the pairs 6 and 6 and my maxi product is 36.
PAIRS WHICH TOTAL 10 & PRODUCT OF THE PAIRS
10,0 = 0 9,1 = 9 8,2 = 16 7,3 = 21 6,4 = 24 5,5 = 25 4,6 = 24 3,7 = 21 2" = 16 1,9 = 9 0,10 = 0
The maxi product lies between 6,4 and 4,6 because it these two numbers have the highest product. 5 x 5=25, 6 ¡¿ 4=24, 4.5 ¡¿ 5.5=24,75. Neither of the products are higher than 25. For my starting number 10, I have used the pair 5,5 and my maxi product is 25.
PAIRS WHICH TOTAL 14 & PRODUCT OF THE PAIRS
14,0=0 13,1 =13 12,2 =24 11,3 =33 10,4 =40 9,5 =45 8,6 =48 7,7 =49 6" =48 5,9 =45 4,10 =40 3,11 =33 2,12 =24 1,13 =13 0,14 =0
The maxi product lies between 8,6 and 6" as this is where the product is highest. 7 ¡¿7=49 7.9 ¡¿ 6.1=48.19 6.9 ¡¿ 7.1=48.99. For my starting number 14, I have used 7,7 and my maxi product is 49.
PAIRS WHICH TOTAL 16 & PRODUCT OF THE PAIRS
16,0=0 15,1 =15 14,2 =28 13,3 =39 12,4 =48 11,5 =55 10,6 =60 9,7 =63 8" =64 7,9 =63 6,10 =60 5,11 =55 4,12 =48 3,13 =39 2,14 =28 1,15 =15 0,16 =0
The maxi product lies between 9,7 and 7,9 as this is where the product ...
