SQR
- Square
Root
Function
SQR(numeric-expression)
The
square
root
function
gives
you
the
positive
square
root
of
the
value specified by the argument.
The
argument
is the value
obtained when the
numeric-expression
is
evaluated.
The
normal
rules
for
the
evaluation
of
numeric
expressions
are
used
here. SQR(x) is equivalent to x 1\(112).
The
value specified by the
argument
may
not
be
negative.
If
you specify a value for the
argument
which
is
less
than
zero.
then
the
message
"BAD

is displayed
and
the

running.
TAN
- Tangent
TAN
(n
umeric'expression)
The
tangent
function gives you the tangent
of
the
argument.
x,
where
x is
an
angle in radians.
The
argument
is the value
obtained
when
the
numeric-expression is evaluated.
The
normal rules for
evaluating numeric
expressions
are
used
here.
If
the angle
is in degrees. multiply the
degrees
by 'IT/180 to
get
the
equivalent angle in radians. You
may
use
(4
*ATN(1))/180
or
0_01745329251994 for
'IT/
180.
Note
that if you
enter
a value of x
where
