I'm looking for a way to change a finite sum of square cosines:
[tex]\Sigma^{N}_{s=1}cos^{2}(x_{s})[/tex]
into a single function of the sum of x:
[tex]f(\Sigma^{N}_{s=1}x_{s})[/tex]
Is there a known way to do this, even if with an approximate method (i.e. Taylor series or such)?. It's ok if it just works in a [tex]\pi[/tex] range.
