Copy the problem below into a text editor or word processor. *
This form accepts only text so a text editor such as Notepad is fine.
*
You might prefer for your own reasons to use a word processor (for example the formatting features might help you organize your answer and explanations), but note that formatting will be lost when you submit your work through the form.
*
If you use a word processor avoid using special characters or symbols, which would require more of your time to create and will not be represented correctly by the form.
*
As you will see within the first few assignments, there is an easily-learned keyboard-based shorthand that doesn't look quite as pretty as word-processor symbols, but which gets the job done much more efficiently.
You should enter your answers using the text editor or word processor. You will then copy-and-paste it into the box below, and submit.

As the intervals become smaller, the percentage of difference becomes larger as a function of the calculation.
