Texas Instruments TI-89 Titanium User Manual

Symbolic Manipulation 263
@n1 ... @n255
ˆ, e
This notation indicates an “arbitrary integer”
that represents any integer.
When an arbitrary integer occurs multiple
times in the same session, each occurrence is
numbered consecutively. After it reaches 255,
arbitrary integer consecutive numbering
restarts at @n0. Use Clean Up
2:NewProb to
reset to @n1.
Note: For @, press:
@89
ˆ represents infinity, and e represents the
constant
2.71828... (base of the natural
logarithms).
These constants are often used in entries as
well as results.
Notes:
For ˆ, press:
@8*
For
e, press:
@8s
A solution is at every
integer multiple of
p.
Both @n1 and @n2
represent any
arbitrary integer, but
this notation identifies
separate arbitrary
integers.
