Limit
(Built-in Mathematica Symbol) Limit[expr, x -> x_0] finds the limiting value of expr when x approaches x_0.
In doing many kinds of calculations, you need to evaluate expressions when variables take on particular values. In many cases, you can do this simply by applying ...
Even simple-looking limits are sometimes quite complicated to compute. Mathematica provides functionality to evaluate several kinds of limits.
$IterationLimit gives the maximum length of evaluation chain used in trying to evaluate any expression.
$RecursionLimit gives the current limit on the number of levels of recursion that Mathematica can use.
In just one Mathematica command, you can easily specify a calculation that is far too complicated for any computer to do. For example, you could ask for ...
LimitsPositioning is an option for UnderoverscriptBox and related boxes that specifies whether to change the positioning of underscripts and overscripts in the way ...
SubMinus[expr] displays as expr_-.
SubPlus
(Built-in Mathematica Symbol) SubPlus[expr] displays as expr_+.
OutputSizeLimit is an option for notebooks which specifies the maximum size in bytes of expressions that will automatically be output in their entirety.
