3-1
Calculations
with
the
Same
Formula
This
unit
is
provided
with
a
very
convenient
function
called
“Function
Mem-
ory”.
This
function
permits
easy
calculations
by
simply
assigning
numeric
values
to
the
variable
as
long
as
the
formula
is
stored
in
advance.
The
following
keys
are
used
for
the
“Function
Memory”.
.. Stores the contents currently written.
.. Displays the stored content.

If
the
stored
content
is
a
formula,
the
desired
numeric
value
will
be
assigned
to
the
used
variables
and
the
calculated
result
will
be
dis-
fou)...
played.
A
simple
example
is
given
below
to
learn
the
use
of
these
three
keys.
Example:
Obtain
the
value
of
y
for
each
of
the
values
assigned
to
x
when
y
=
3.43
Cosx.

As
shown
in
this
example,
the
“Function
Memory”
is
ideal
for
calculating
a
ormula
in
which
only
the
numeric
values
assigned
to
a
variable
differ.
Example:
Obtain
the
value
of
V
for
the
respective
values
of
r
when
V
=
4/3ar°.

late in three decimal places by rounding off.)
