To Integrating Equations:
To integrate an equation:
1.
If the equation that defines the integrand's function isn't stored in the
equation list, key it in (see "Entering Equations Into the Equation List" in
chapter 6) and leave Equation mode. The equation usually contains just
an expression.
2.
Enter the limits of integration: key in the
lower
limit and press
,
then key in the upper limit.
3.
Display the equation: Press
{
G
and, if necessary, scroll through
the equation list (press
z
or
z
)
to display the desired
equation.
4.
Select the variable of integration: Press
{

variable.
This starts the
calculation.

You can halt a running integration calculation by pressing

However, no information about the integration is available until the
calculation finishes normally
The display format setting affects the level of accuracy assumed for your
function and used for the result. The integration is more precise but takes
much
longer in the {
} and higher {
%
}, {
}, and {
} settings. The
uncertainty
of the result ends up in the Y–register, pushing the limits of
integration up into the T– and Z–registers. For more information, see
"Accuracy of Integration" later in this chapter.
