Binomial approximation was used in this maths lesson on binomial expansion and Pascal's triangle. Before binomial approximation, (a+b)^7 was expanded using Pascal's triangle. Pascal's triangle was used to expand (a+b)^7 in ascending powers of x up to the term with x^3.
This lesson on binomial approximation answered questions such as what is binomial approximation, how to find an approximation in binomial expansion, and how to use Pascal's triangle to expand binomials.
