Information about the exam

For general information about exams, and the exam timetable, please see the University's examinations web page.

The Math3061 exam is scheduled for 13:50-16:00 on Friday November 11, 2016. The exam has six questions, three questions for each of the geometry and topology components of the course. Each question may be attempted. The exam is worth 66% of your final assessment.

Please note that the questions for the geometry and topology sections of the course must be answered in separate booklets.

The exam is based on all the material covered in lectures, tutorials, assignments and the quizzes. The best way to prepare for the exam is to read through and think about your lecture notes and then to try to solve as many questions as possible (without looking at the solutions) from the lectures, tutorials and assignments. You might like to look at the 2013 Math3061 exam. Here are the solutions to this exam:

geometry solutions topology solutions

We recommend that you do not look at these solutions until you have first attempted to do all of the questions in the exam.

In addition, here are the questions for the 2014 exam. Parts of this exam were discussed in lectures so we will not be posting solutions for this exam. (See the discussion Question 7b on Ed-Stem.)

Course outline

The course will closely follow the "Geometry" lecture notes by O'Brian.

Week 1
Reading for Week 1: pages 1-29, but not the section on Symmetries. [The coordinate formula for a halfturn does not appear in this part of the O'Brian notes. FYI, the image of a point (x,y) under a halfturn about point P(p,q) is (2p-x,2q-y).]
Week 2
Reading for Week 2: pages 30-36. Handout on properties of rotations from lecture 6.
Week 3
Reading for Week 3: pages 37-40, omit Chapter 3, then pages 51-56.
Week 4
Reading for Week 4: pages 57-58 and pages 67-70 of Chapter 4, omit the remainder of Chapter 4 and all of Chapter 5, then pages 97-99.
Week 5
Reading for Week 5: pages 100-107.
Week 6
Reading for Week 6: page 113 to first half of page 121. Handout end of proof from the last Geometry lecture.
Topology is the study of surfaces under continuous deformation. That is, we allow ourselves to stretch surfaces but not to tear them.

Week 7
Graphs, subdivision, sums of degrees = twice the number of edges, connectedness, circuits, trees.
Week 8
Disc, annulus, torus, Möbius band, Klein bottle, sphere, projective planes, homeomorphism, stereographic projection.
Week 9
Triangulated surfaces, Euler characteristic, invariance under subdivision, cutting, pasting, boundaries, orientation, edge equation.
Week 10
Classification of surfaces, genus, oriented closed surfaces in three dimensions, handles, crosscaps.
Week 11
Platonic surfaces. Graphs on surfaces: K5 is not planar. Map colouring: the five colour theorem, the Heawood estimate for maps on surfaces.
Week 12
Knots: Polygonals knots, knots diagrams, the unknot, trefoil knots, figure eight knots, knot colouring.
Week 13
Knot determinants, n-colourings, Seifert surfaces and knot genus.
