  1. If you are not familiar with the graphing of functions on the TI-85, then first read the Initial Setup page from Little's Basic Guide to the TI-85.
  2. Press the GRAPH key and then pick y(x)= by pressing the F1 key.
  3. If necessary, keep pressing the F4 key until only y1= appears on the screen.
  4. At the prompt y1=, type in

    sin x^2

    and press the ENTER key.

  5. At the prompt y2=, type in

    fnInt(sin T^2,T,0,x)

    and press the ENTER key. You can enter fnInt by pressing the 2nd CALC keys followed by the F5 key to choose fnInt.

  6. The range settings for the graph above is  [-3, 3] × [-1, 1]:

  7. Pick GRAPH from the menu by pressing the F5 key. The graph of f is:
