Limit
A function 
is said to have a limit 
if, for all 
, there exists a 
such that
whenever 
.
A Lower Limit
is said to exist if, for every
, 
for infinitely many values of 
and if no numberless than 
has this property. An Upper Limit
is said to exist if, for every
, 
for infinitely many values of and if no numberlarger than 
has this property.Indeterminate limit forms of types 
and 
can be computed with L'Hospital's Rule. Types 
can be converted to the form 
by writing
Types
, 
, and 
are treated by introducing a dependent variable 
, then calculating lim 
. The original limit then equals 
.See also Central Limit Theorem, Continuous, Discontinuity, L'Hospital's Rule,Lower Limit, Upper Limit
