To
combat cheating, while taking the exams
1)students must show their ID upon entering
the classroom,
2) no cell phone use,
3) if a student leaves the room during test time, e.g.Men¡¯s/Ladies¡¯ room,
he/she forfeits finishing the exam.
How to put in numbers
at the HW website
a)
Significant digits and precision
The
computer carries out all calculations to at least six significant digits. Do
not use "significant figures" algorithms to round off your answer. Do
not round off 'intermediate' calculations. Six digits are shown in solutions.
To be scored as correct, an answer must be within 1% of the computer's answer
(except for an answer of zero, which must be exact). You will be informed of
any exceptions to this tolerance.
b)
Scientific/Engineering notation ("times 10 to the power")
Very
large or very small numbers may be input with "scientific notation,"
e.g., +3.56e-10, which is 3.56 times ten to the negative tenth power. However,
468 (or 468.0) is just as good as +4.68e+02 or +4.68E+02.
