Expanding functions in increasing powers

Click For Summary
To expand the function f(x) = (1+x)^3 in increasing powers of x, start by multiplying the expression: (1+x)(1+x)(1+x). This involves first calculating (1+x)(1+x) to get 1 + 2x + x^2, and then multiplying that result by (1+x) again. The final expansion results in 1 + 3x + 3x^2 + x^3. This method provides a clear step-by-step approach to expanding functions in increasing powers.

I have not been taught how to do this and therefore unable to answer the following question :-

Expand the function f(x) = (1+x)^3 in increasing powers of x ?

Please help

Hi struglnstudnt! :smile:

You need to calculate

(1+x)^3=(1+x)(1+x)(1+x)

Just work out the brackets...
