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 or
or in an algebraic extension (e.g.
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 independant.
Normal form : normal
- Unlike simplify,
normal does not try to find algebraic relations between
transcendental functions like
cos(x)2 + sin(x)2 = 1.
- It is sometimes necessary to run the normal command twice to
get a fully irreducible representation of an expression
containing algebraic extensions.
