    Approximation of cos(cos(x))

    Approximation of cos(cos(x))

    Hello out there. I'm wondering, if it is possible to make some kind of approximation to the function: f(x)=Cos(Cos(x)). If I graph it, it gives me a function that looks like one of the form g(x)=A\[\cdot\]Cos(ωt+θ)+φ. How do I mathematically make the reduction from f(x) to g(x). Best Andreas
