    [SOLVED] function

    Let f be a function such that f(n+1)=1-[f(n)]^2, \forall n\in\mathbb{Z}, n\geq0. How would f(n+2) be expressed in terms of f(n)?

    f(n+1)=1-[f(n)]^2

    \implies f(n+2) =  f\left\{(n+1)+1\right\}=1-[f(n+1)]^2 = 1 - \left\{ 1-[f(n)]^2 \right\}^2

    Which step do you disagree with, particularly?

    I don't disagree with that but when your response was first .... I was in disagreement.

    Oh yeah that, haha.

    When I am fairly certain I know the answer, I like to secure my position.

    Cheers!
