is
normal
to
set
the
angular
mode
to
“RAD”
when
executing
integral
of

May
take
much

time
to
raise
the
accuracy

Error
may
be
large
even
when
much
execution
time
has
been
consumed.

("E”

In
such
cases,
dividing
the
integral
intervat
will
reduce
execution
time
and
raise
accuracy:
3.
If
the
result
varies
greatly
when
the
integral
interval
is
moved
slightly.
Divide
the
interval
inta
sections
and
sum
up
the
results
obtained
in
the
sections.
2.
For
a
periodic
function
or
if
the
value
of
integrai
becomes
positive
or
nvgative
depending
on
the
interval:
Calculate
for
each
period
or
Separately
for
the
sections
where
the
result
of
inte-
gral
is
positive
from
where
the
result
is
negative,
and
sum
up
the
results
obtained,
3.
If
long
execution
time
is
due
to
the
form
of
the
function
defined
Divide
the
function,
if
possible,
into
terms,
execute
integral
for
each
term
sepa-
rately,
and
sum
up
the
results.
