I wonder in what circumstances:(adsbygoogle = window.adsbygoogle || []).push({});

given a function g, we can analytically find the coefficients [tex]a_{i,j}[/tex]

[tex]g(x1+x2)=\sum a_{i,j}g(x^ix^j)[/tex]

I'm not if this would server any useful applications but the transformation looks interesting to me. It looks very simmilar to a polynomial transformation.
