2.2.1, 2.2.2;
2.3.2-5 (2.3.4 doesn't need to be elegant, and it can be computer generated, if that's easier for you);

Hint for 3.7.1-4: If you 'walk around' the triangle ABC, going from A to B to C back to A, are you walking clockwise or counter-clockwise? What about when you walk around f(A)f(B)f(C)?

Due Wednesday, October 26:  
4.4.1-4;
4.5.1-2;
4.6.1-4;
Find two examples of properly handled perspective in painting, sketches, etc.; find two badly handled examples. You can create your own examples if you're artistically inclined, but your bad examples shouldn't be just generally bad art - the perspective should be the main problem.
Some examples: You can look here for inspiration, but need to find your examples elsewhere. PhotoshopDisasters' perspective section has some fun examples. Less disastrous examples of digital manipulation of perspective in Photoshop are given in the tutorials architectural photo tutorial and landscape photo tutorial. David Hockney's photographic collages mess with perspective - the individual photos are shot from wildly different perspectives.
Google's Art Project is a fantastic source of images. You are very welcome to find your examples here.

Homework teams
You are not only allowed, but encouraged, to work with classmates on the homework, and could divvy up the exercises among members of your study group. Unfortunately, it sounds like every team member needs to submit their own copy of the assignment.
