DECM
Returns the number of possible sets of
y
items
taken x at a time. No item occurs more than
once in a set, and different orders of the same x
items are not counted separately.

DECM
Changes the sign of

plex conjugate of x
c
.
CORR

DECM
Returns the correlation coefficient for the current
statistical data and curve fitting model.
COS

DECM Returns the cosine of the angle in X .
COSH

DECM Returns the hyperbolic cosine of x .
COV

DECM
Returns the population covariance for two data
sets. It depends on the fit model selected. For
LinF, it calculates

DECM
Recalls the date from the real time clock and
displays it in the numeric section in the format
selected. See D.MY, M.DY, and Y.MD.
The function DATE of HP-12C corresponds to
DAYS+ in your WP 34S (see below).

DECM
Works like DATE in HP-12C , adding
x
days on a
date in Y in the format selected and displaying
the resulting date including the day of week in
the same format as WDAY does.
