method and places
result in display (X-
register). Computes
the correlation
coefficient (r) of the
linear estimate data
by measuring how
closely the data pairs
would, if plotted on a
graph, represent a
straight line, and
places result in Y-
register (Page 46).
L
Linear
regression. Computes
y-intercept (B) and
slope (A) for linear
function y = Ax + B
that best
approximates x- and
y-values accumulated
using z. The value
of the y-intercept is
placed in the X-
register; the value of
the slope is placed in
the Y-register (Page
45).

Storage

O
Store. Followed
by register address (0
through 9), stores
displayed number in
the storage register
specified. Also used
to perform storage
register arithmetic
(Page 29).
l
Recall.
Followed by address
(0 through 9), recalls
number from storage
register specified into
the display (X-
register) (Page 29).
Q
CLEAR Clears
contents of the stack
and all storage
registers to zero
(Page 30).
K
Recalls
number displayed
before the current
operation back into
the display (X-
register) (Page 22).

Trigonometry

D
Sets decimal
degree mode for
trigonometric
functions—indicated
by absence of GRAD
or RAD annunciator
(Page 34).
R
Sets Radians
mode for
trigonometric
functions—indicated
by RAD annunciator
(Page 35).
g
Sets Grads
mode for
trigonometric
functions—indicated
by GRAD annunciator
(Page 35).
[ \ ]
Compute sine, cosine,
or tangent,
respectively, of
number in display
(Page 35).
, { /
Compute arcsine,
arccosine, or
arctangent,
respectively, of
number in display
(Page 35).
