5.12.13  Normal form : normal

normal takes as argument an expression. The expression is considered as a rational fraction with respect to generalized identifiers (either true identifiers or transcendental functions replaced by a temporary identifiers) with coefficients in ℚ or ℚ[i] or in an algebraic extension (e.g. ℚ[√2]). normal returns the expanded irreducible representation of this rational fraction. See also ratnormal for pure rational fractions or simplify if the transcendental functions are not algebraically independent.
