Assumptions

FilledSmallSquare Assumptions is an option for functions such as Simplify, Refine and Integrate which specifies default assumptions to be made about symbolic quantities.

FilledSmallSquare The default setting is Assumptions:>$Assumptions.

FilledSmallSquare The assumptions can be equations, inequalities or domain specifications, or lists or logical combinations of these.

FilledSmallSquare Assuming modifies $Assumptions and so modifies the value of default settings for Assumptions options.

FilledSmallSquare x Reals can be used to specify that x should be treated as a real variable.

FilledSmallSquare See Section 3.5.8.

FilledSmallSquare See also: Assuming, $Assumptions, GenerateConditions, Integrate, Refine, Limit.
