Simplify
Simplify[
expr
] performs a sequence of algebraic transformations on expr, and returns the simplest form it finds.
Simplify[
expr
,
assum
] does simplification using assumptions.
Simplify tries expanding, factoring and doing other transformations on expressions, keeping track of the simplest form obtained.
The following options can be given: Assumptions can consist of equations, inequalities, domain assertions such as x
Integers, and logical combinations of these.
Example: Simplify[Sqrt[x^2], x
Reals]
 .
Simplify can be used on equations, inequalities and domain assertions.
Example: Simplify[x^2 > 3, x > 2]
 .
Objects that are specified as satisfying inequalities are always assumed to be real.
Example: Simplify[x
Reals, x > 0]
 .
FullSimplify does more extensive simplification than Simplify.
