Just wondering how much we'll need to know for the mid-term, upto what unit, for instance? Occasionally the more complex equations have been called extraneous since algebra is not prerequisite. Will calculators be necessary/permitted?
The last section we covered was about fractals. There was a handout given some time ago listing the sections in the book and describing how they correspond to the lectures. Calculators will not be permitted (nor needed) for the exams.
will we need to know the Other Transformations of the plane for the midterm (such as the squaring transformation or the moebius) ?
You do not need to memorize them. If they appear in the midterm, their definitions will be provided.
dividing a line segment such that one part is twice longer than the other:
if we have a line seg AB and we divide it into 3 equal parts (denoting the cuts as C and D), we could then remove D, such that CB were now twice longer than AC: is this an acceptable way to do it or is erasing D a rule-breaker?
No need to erase anything (if you do, then perhaps it would not be clear how you got your points). You would need to say that C is the point that divides the segment as needed.
In the solutions for Midterm exam Feb 2006 (question 2b), the word "duplicating" is used to mean "doubling". I just want to be sure to avoid confusion: Duplicate means copy, not double, right?
Yes, you are right. Slip. Should have been "doubling".
on the october 16th 2003 midterm posted online part b of the first question asks to construct an equilateral triangle of angle B over a given base. The problem is that equilateral triangles have 3 angles of 60 degrees, while angle B is about 32 degrees. Is this a mistake? If so, what should the question read?
do you know when the mid-term results will be posted?
Sometime next week before the Thursday class.
