### Extra Credit Opportunities

Extra Credit is something that is related to the class and would be good
to do, but not required due
to time constraints.
**I advise that you spend time revising your Ben F and mathematician writing
assignments and taking WebCT quizzes 6-9 before you think about
extra credit.**
From the syllabus: There will be other extra credit opportunities during the semester for which points will accumulate. When final grades are given, extra credit points are taken into account in the determination of -,nothing or + attached to a letter grade.

Research
and report back as to whether the golden mean is also thought of as
beautiful and aesthetically pleasing in non-Western cultures

Find and attend a real-life debate.
Extra credit if you summarize the debate and
give some examples of how statistics and
critical thinking methods were used in the debate.
(ie were stats used to back up a point?
What stats were quoted?
Did they twist the stats for their own use?)

Provide several real-life situations - ideally, from your own
experience - for which some of our strategies of
thought and inquiry would provide effective methods for approaching and
resolving them.

Beachball activity
to prove that the sum of the angles of a spherical triangle is always
greater than 180 degrees

Extra Credit Problem
on the geometry of the earth and universe

Show that

x = cos(a) sin(b)

y = sin(a) sin(b)

z = cos(b)

satisfies the equation x^2 + y^2 +z^2 = 1

Recall that we used the above coordinations to show that the surface of a
sphere is 2D because it only requires longitude and latitude.

Choose a mathematical topic that you are interested in that we
have not covered, research to find numerous references on it, and then
write up a report in your own words.
(For example, What is a fractal)

Anything that I mentioned would count for extra credit over
the course of the semester.
