Limit
 Usage
• Limit[expr, x-> ] finds the limiting value of expr when x approaches  .
Notes
• Example: Limit[Sin[x]/x, x->0]  . • Limit[expr, x-> , Direction -> 1] computes the limit as  approaches  from smaller values. Limit[expr, x-> , Direction -> -1] computes the limit as  approaches  from larger values. • Limit returns Interval objects to represent ranges of possible values, for example at essential singularities. • Limit returns unevaluated when it encounters functions about which it has no specific information. Limit therefore by default makes no explicit assumptions about symbolic functions. • Assumptions can be specified as a setting for the option Assumptions. • New in Version 1; modified in 5.
