Pascals Triangle

Combination values are derived from pascals triangle. This is part of the Prelim Maths Extension 1 Syllabus from the topic Combinatorics: Working with Combinatorics. In this post, we will explore The binomial expansion and Pascal’s triangle pascals triangle. Here we will learn to note the pattern formed by the coefficients of $x$ in the expansion of $(1+x)^n$ and recognise links to Pascal’s triangle.
