Hi Oliver,

what means "write that function in detail" ? A power series ?
an infinite one with all areas in the complex plane where the
series is not convergent? Or a rational approximation ?
Or the definition of the function ? Perherps you can give an
example what the  "write that function in detail" mean for you
for the well known Sin[] function.
