lim
Type: Function
Description: Returns the limit of a function as its argument approaches a specified value. Expands and
simplifies an algebraic expression.
Access: Calculus, !Ö LIMITS & SERIES
Input: Level 2/Argument 1: An expression.
Level 1/Argument 2: An expression of the form x = y, where x is the variable and y is the value at
which the limit is to be evaluated. If the variable approaching a value is the current CAS variable,
it is sufficient to give its value alone. The ∞ symbol provided by the calculator can be used to set
the limiting value at plus or minus infinity.
Output: The limit of the expression at the limit point.
Flags: Exact mode must be set (flag –105 clear).
Numeric mode must not be set (flag –3 clear).
Radians mode must be set (flag –17 set).
Example: Find the following limit:

Command: lim ((X^N-Y^N)/(X-Y), X=Y)
Result: N*EXP(N*LN(Y))/Y

LIMIT
Type: Function
Description: Returns the limit of a function as its argument approaches a specified value. This function is
identical to the lim function, described above, and is included to ensure backward-compatibility
with the HP 49G calculator.

Type: Command
Description: Linearizes expressions involving exponential terms.
Access: …× or Exponential and logarithm, !Ð or P ALG , or !Ú REWRITE , or
PL EXPLN .
Input: An expression.
Output: The linearized expression.
Flags: Exact mode must be set (flag –105 clear).
Numeric mode must not be set (flag –3 clear).
Radians mode must be set (flag –17 set).
