Are we allowed to use our permapaque markers in the exam to highlight different steps in constructions?
Yes; no problem with using markers.
The last object in Question #4 of the 2007 Spring midterm lists a reflection of the bird image, however, each of the birds is facing the same way. Wouldn't that mean that the only symmetries are identity and translation?
In fact, the inserted figure a wrong: every second bird should face the other way. That is why the basic translation vector is so long. With the design shown there, you are right: there are no reflections.
Will there be any questions resembling #5b in the 2007 midterm...the stretching factor of the Sierpinski triangle?
No; we have not covered fractals yet.
Will we be allowed to use calculators for the sections pertaining to Fibonacci numbers?
No calculators willl be allowed.
How would one go about constructing the perpendicular line segments for the beginning of a golden rectangle?
Construct the perpendicular to the base of the rectangle and passing through the end-point of the base. That construction is in the notes and in the textbook.
How would you solve the following Fibonacci sequence:
f19 = 4181 and f22 = 17711. What is f20 and f21?
The solution for constructing a Golden Rectangle is simpler in the textbook than the construction we did in class. Which should we be using on the exam?
1. Fibonacci question: solve
f21 = f20 + 4181
17711=f21 + f20.
2. Golden rectangle: whichever you want (clearly written and correct).
So the answer to the Finonacci question is 17711=f21 + f22. We don't need to specify what the quantities of f21 and f22 are?
No. You need to solve the system of the two equations you see above, where f20 and f21 are the unknowns. The final answer should be two specific numbers, one for f20 the other for f21.
So what are the next steps in solving the problem?
I had trouble with this in grade school as well
Put f20+4181 in place of f21 in the second equation: get one equation with one unknown (f20). Solve that equation to get the value of f20, then plug that in the first equation to get the value for f21.
when will the answers to the midterm exam be posted?
After the deferred midterm is over (likely to happen some time coming week).
