SIMPLIFY

Syntax

SIMPLIFY( equation|expression, "simplification"[;"simplification"])

Implemented in iMath since version 2.2.0 or earlier.

Possible values for simplification are:

expand Fully expands all expressions, including function arguments.
expandf Only expand function definition, not arguments.
eval Numerically evaluate the equation as far as possible.
normal Normalize the equation (see description of GiNaC normal() method for details).
collect-common Collect common factors (see description of GiNaC collect_common_factors() method for details).
unsafe Does unsafe simplifications, for example sqrt{x^2} => x or \arctan\tan{x} => x. Note that the opposite \tan\arctan{x} => x is not an unsafe evaluation and is thus done automatically (by GiNaC).
ignore-units Removes units from certain functions, so that scientific formulas evaluate properly. Currently only units in the arguments of log and ln are handled.
diff Evaluates differential function diff, thus symbolically calculating differentials as far as possible.
cancel-diff Dissolve all derivatives into fractions of single differentials, and cancel numerators and denominators wherever possible. A typical use would be integration by separation of the variables.
sum Evaluates sum functions, thus symbolically calculating sums as far as possible.
gather-sqrt Gathers single square roots under one root symbol.
integrate Symbolically integrates any integrals in the expression as far as possible.
