In order to view homework scores, go to
- CID is your 3-digit CID
- PASS is your 4-character password
- N is the homework number
Interpreting the results:
- If an numerical answer is incorrect, I
usually give you an order of magnitude estimate of your error.
- If your answers are wrong by a minus sign
or are exactly off by factors of 10 or 2, these are also indicated.
- If the message says "Error," this is a
Maple error. See specific error messages below.
Common Maple Errors:
- cannot determine if this expression is true
or false Usually this means that Maple
cannot numerically evaluate your expression. 1) You may be using a variable in
the answer that I have not defined in the worksheet. The easiest fix is to
enter the numerical answer from your Maple worksheet. 2) You may have an
invalid character that you accidentally cut and pasted from Maple. See if
the expression looks like what you entered. If you see a square, for
example, this is the likely problem.
- missing operator or
';' Your syntax is in error. You may have left out a
multiplication sign. Implicit multiplication is not accepted. That is, write
'A*B', not 'A B'.
- := unexpected You probably typed in := that was not needed because it was already
provided in the answer. Check the format of the answer on the submission
form. If something like "P:=" appears before the text box, don't type that
into the text box.
- : unexpected
or ; unexpected Maple was waiting for further information when it reached the end of the
line. This message occurs, for example, if your parentheses are unbalanced
or if you just put a "-" in the text box.
unexpected You have a character in your string
that Maple cannot interpret.
- unexpected number
Did you leave out a * in your answer, as in 3.56 10^7 rather than 3.56*10^7
