Figure 1 is the result of pressing
the ![]() ![]() ![]() ![]() |
![]() | Figure 2 shows the program window after we havee responded to the
two prompts that the program gives us. First, the program asks us
for the DIVISOR VECTOR. We respond with
![]() ![]() |
![]() | The polydiv program displays the initial matrix in Figure 3.
At this point the initial division has been done. That is, the program
reflects the problem at the stage of completing the initial division, namely,
![]() ![]() |
![]() | In Figure 4 the program has taken another step, determining the
second coefficient in the quotient. In this case, that is really all that there is to the
problem. Again the program is in a paused state so that we can move around in the
matrix if need be.
For this problem we can see all of the answer on the screen.
Therefore, we do not need to look at any hidden values. We press
![]() |
![]() | Once the program has reached the end of the division, the polydiv
program displays
the menu shown in Figure 5. This allows us to
start a new problem by pressing 0 end the POLYDIV1 program by pressing 1 show the answer to the last problem by pressing 2. |
Let us look at another problem, namely,
![]() | We left Figure 5 by pressing the
![]() ![]() |
![]() | Pressing ![]() ![]() |
![]() | Figure 8 shows the calculator display after the second cycle
of the division algorithm. The second coefficient of the quotient
has been computed to be " 1" and
the corresponding portion of the division algorithm has been completed.
Press
![]() |
![]() | In the earlier Figures we could see all that we needed to see on the
screen.
Now, in Figure 9, we can see some of the values but we are missing the
bottom numbers. Because the program is paused, we can use the cursor keys to
move around on the screen. For example,
we can press the ![]() |
![]() | Figure 10 displays the bottom of the matrix. Now that we can see the bottom of the matrix we note that the problem is done. If we press the ENTER the program will display the options to do a new problem, quit, or re-display the current matrix. |
Here is one more example:
![]() | In Figure 11 we have pressed ![]() |
![]() | Press ![]() ![]() |
![]() | Having seen the entire DIVIDEND,
we press ![]() |
![]() | Figure 14 shows the matrix after the second step of the division algorithm. The second coefficient of the quotient has been computed to be " 6". |
![]() | To move from Figure 14 to Figure 15 we
press ![]() |
![]() | Then, in Figure 16, we use the
![]() ![]() ![]() |
![]() | At this point all of the updates from the program are happenning in matrix cells that are off the screen. We can use the cursor keys to move the display around so that we can see more of the matrix. |
![]() | Figure 18 shows the bottom right side of the matrix.
We press ![]() |
![]() | Here we chose option 1 to end the program. Had we chosen option 2 the program would have re-displayed the matrix so that we could rove around it to see all of the values. |
