Is there a way to access the tables that Sum[] uses to simplify summations into known functions like for example Sum[Exp[-a* n^2], {n, -Infinity, Infinity}] is simplified into EllipticTheta[3, 0, E^(-a)] Is there a way to use the table in reverse, to approximate a known function? I am not interested in the above example, so please do not tell me how I can approximate EllipticTheta[]... I am a rather naive Mathematica user, so please be explicit. Thank you. O
