- Exam 1
- Wednesday, Feb. 25
- Material since beginning of course, e.g., rays, intersections, transformations, homogeneous coordinates, related algorithms, etc.
- 3 - 5 short-answer questions
- Whole class period
- Open references (books, notes, computers for reference), closed person
- Colloquium today, 4:00 - 5:00, Newton 201
- Dickerson, “Mathematics Majors’ Understandings of the Concept of Mathematical Definition”
- Extra credit for summaries
- Define coordinate system with one vertex of triangle as origin
and adjacent sides as basis vectors
- Point is in or on triangle if its β and γ coordinates satisfy β ≥ 0, γ ≥ 0, β + γ ≤ 1
- Find β, γ, and t for intersection by solving system
of equations arising from s + td =
β(b-a) + γ(c-a) + a
