for values of x near 0.

Using Microcalc:

1. Choose Beginning Calculus from the initial menu and press .
2. Use the arrow keys to move to the menu item Limit of F(x), press and .
3. At the prompt F(x) =, enter the function sin( /(16 x)) The two keys and must be pressed at the same time. This will give the Greek letter pi.
4. At the prompt a = , enter 0 .
5. At the prompt h = , enter 1 .
6. You will then see on the screen F(a+h) = 0.19509 032
7. Press and use the arrow keys to move to h <<-- 1/2 h and press .
8. If you keep repeating the previous step then you will obtain a table as below:

   __________________________________________________________
   
       N          a + h/2^n       F(a + h/2^n)

      10   9.76562 500 e-04        0.00000 000
   
   On the evidence of all values of  F  calculated so far,
   we estimate  Lim  F(x) =  -3.89125 750 e-08
                x->a+

9. If you want to see the behavior for x < 0, press after seeing the values above, use the arrow keys to move to Change h and press .
10. At the prompt h = , type -1 and proceed as above.
