Answers to Questions
How to create a pascal triangle?
The principle of Pascal triangle is based on a triangular contruction, write 1 on the first line, and 1 1 on the second line.
For the next lines, add the values of the two numbers directly above.
Example: Start of the Pascal Triangle :
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
1 6 15 20 15 6 1
1 7 21 35 35 21 7 1
Values can be calculated using binomial coefficient, also used in calculation of combinations.
Pascal triangle values can be compared to the Fibonacci sequence where each number is the sum of the two preceding numbers.
How to calculate a precise value in the Pascal's triangle?
A value \( V \) of the Pascal triangle at the position (line A, column B) can be calculated with the binomial coefficients (and thus with factorials) and the formula $$ V = \ binom {A} {B} = \ frac {A!} {B! (A-B)!} $$
How to create a Pascal Triangle with Excel?
Write 1 in the cell B1, and =A2+B1 in the cell B2 and copy the contents in as many cells as you wish but do not touch column 1 and line 1. Each line is a new row of the Pascal triangle.
