0.0/2.0 points (graded)
In this multiple part question, check the boxes on any correct statements. Consider both questions before clicking
"Submit" - the grader will only tell you if you correctly checked the correct box or boxes and left the other box or
boxes unchecked. Unfortunately, no partial credit can be given in such a question, though we can allow you multiple
attempts, here 2 attempts.
Which of the following lists of numbers is a complete collection of all the 6th roots of unity, with no duplications (i.e.,
where each complex number when written in the form $a + ib$ appears only once in the list)? (The complete collection
of all the 6th roots of unity would contain all those distinct and possibly complex numbers that, when raised to the
sixth power, give the result 1.)
Select all correct lists
$\exp(2\pi i s/6); s = -3, -2, -1, 0, 1, 2, 3$
$\exp(2\pi i s/6); s = 18, 19, 20, 21, 22, 23$
