[Press here to see animation again!]

  1. Enter the function: Y = sin 2x and press the ENTER key.
  2. Press 2nd MATH and pick MISC by pressing F5.
  3. Press F3 to enter seq. Continue to enter the command:

    seq(10^I, I, 0, 10, 1) STO x

    and press the ENTER key.

  4. This creates a list of x-values:

    {1 10 100 1000 ... 10000000000}

    which are the powers, 10I, for I = 0, 1, ..., 10.

  5. Press the EXIT key twice.
  6. Type Y and press the ENTER key. On the screen you will then see the list of corresponding y-values using the function you entered above:

    IxY
    010
    1100
    21000
    310000
    4100000
    51000000
    610000000
    7100000000
    81000000000
    910000000000
    1010000000000

    It appears that the limit is 0 but this incorrect; however, the limit does not exist.
