Simplifying Formulas
====================

The `a s' (`calc-simplify') [`simplify'] command applies various
algebraic rules to simplify a formula.  This includes rules which are
not part of the default simplifications because they may be too slow
to apply all the time, or may not be desirable all of the time.  For
example, non-adjacent terms of sums are combined, as in `a + b + 2 a'
to `b + 3 a', and some formulas like `sin(arcsin(x))' are simplified
to `x'.

The sections below describe all the various kinds of algebraic
simplifications Calc provides in full detail.  None of Calc's
simplification commands are designed to pull rabbits out of hats;
they simply apply certain specific rules to put formulas into
less redundant or more pleasing forms.  Serious algebra in Calc
must be done manually, usually with a combination of selections
and rewrite rules.  See Rearranging with Selections.
See Rewrite Rules.

See Simplification Modes, for commands to control what level of
simplification occurs automatically.  Normally only the "default
simplifications" occur.
