1. Come up with another topology (that is, one not discussed in class) on the real line and show it is not the same as the standard topology.
2. Give 3 different topologies on the set of four points.
3. Section 1.1: Problems 19 and 23 (for 23 use the subspace topology of the standard topology on the plane)
4. Section 2.1: 2,3,4,6,7,8,12
