IV. Special Graphs

C. Integral

The TI-89 will graph the integral of a function. You may wish to see the graph of an integral in a calculus application. However, the values of the integral may be quite large and you will need to use care in selecting a window. Also, the graphs may be generated slowly. You will need to use the nInt(x) function.

Example: Graph .

Press to
access the Y=Editor.
Press and scroll
to A:Calculus.

Press and to scroll
to B:nInt(. and press
ENTER.

Notice the format of the
function. The graph for
this will graph from x=-2
to the value of xmax.
Press to
draw the graph.
