SOAR Homework Seven
These homework problems are meant to expand your understanding of what
goes on during class. Any you turn in will be graded and returned to
you. Answers may or may not be posted on the web, depending on demand.
 Repeat the construction for a Koch snowflake, except now use the

Find and read a copy of Edwin Abbot Abbot's classic book
``Flatland: A Romance Of Many Dimensions'' (originally published in
1884). The text should be available at your local library, and it
is available online at
http://www.alcyone.com/max/lit/flatland/. It is written from
the perspective of the narrator, A. Square, living in a
twodimensional space and trying to come to grips with the ``third
dimension.'' It is written for a late19thcentury audience
starting to come to grips with the new idea of the possibility of a
fourth dimension. And, yes, there are two Abbots in his name.

Do as many of the problems from the handouts on logarithms or
complex numbers as you like. (I will accept problems from each, even
though the answers are given on the logs handout. This just means
you have to show me some steps on the way.)
These problems are also available as a pdf file.
