DOMAIN — You specified an argument to a function outside
the valid range. For example:
•For xÑy: x = 0 or y < 0 and x is not an odd integer.
•For yx: y and x = 0; y < 0 and x is not an integer.
•For Ñx: x < 0.
•For LOG or LN: x { 0.
•For TAN: x = 90Ä, -90Ä, 270Ä, -270Ä, 450Ä, etc., and
equivalent for radian mode.
•For SIN-1 or COS-1: |x| > 1.
•For nCr or nPr: n or r are not integers | 0.
•For x!: x is not an integer between 0 and 69.
EQUATION LENGTH ERROR — An entry exceeds the digit
limits (80 for stat entries or 47 for constant entries); for
example, combining an entry with a constant that exceeds the
limit.
FRQ DOMAIN — FRQ value (in 1-Var stats) < 0 or > 99, or
not an integer.
OVERFLOW — |Á| ‚ 1¯10, where Á is an angle in a trig,
hyperbolic, or R ´Pr( function.
STAT — Attempting to calculate 1-var or 2-var stats with no
defined data points, or attempting to calculate 2-var stats
when the data lists are not of equal length.
DIM MISMATCH — Attempting to create a formula when the
lists are not of equal length.
FORMULA — The formula does not contain a list name (L1,
L2, or L3), or the formula for a list contains its own list name.
For example, a formula for L1 contains L1.
SYNTAX — The command contains a syntax error: entering
more than 23 pending operations or 8 pending values; or
having misplaced functions, arguments, parentheses, or
commas. If using q, try using W.
INVALID FUNCTION — Invalid function entered in the
function table.
