I have 6 huge expressions I want to integrate. Is there any way to break them piecewise and then send them for integration? Two sample expression are: Expression 1: -((Sqrt[1 - cp^2] Sqrt[1 - cq^2] E^(-((Ep^2 + Eq^2 - 2 m^2)/( 2 \[Sigma]^2))) (Ep - m) (Ep + m) (-Eq + m) (Eq + m) \[Pi]^2 (3 Ep Eq - 2 cp^2 Ep Eq - 2 cq^2 Ep Eq + 3 cp^2 cq^2 Ep Eq + cp^2 Ep m + 2 cq^2 Ep m - 3 cp^2 cq^2 Ep m + 2 cp^2 Eq m + cq^2 Eq m - 3 cp^2 cq^2 Eq m + 3 m^2 - cp^2 m^2 - cq^2 m^2 + 3 cp^2 cq^2 m^2 - 2 cp cq Sq...
