## 0.3 Pascal's Triangle

Now we can produce something much more dramatic.

Set up a new sheet with the integers around the edge as before. This time put
in d5: '=d4+c4'and copy it into a huge rectangle from d5 to cc100 (say). You
should get a huge mass of zeroes. Now set c4 = 1. What do you find?

You should find **"Pascal's Triangle" **or the **binomial coefficients.**

**Exercise 0.5 Do this and answer the question which is larger, the binomial
coefficient C(15,5) or C(14,6)?** Solution
