Assignment
Part 1: Write a complete proof for Croom Ch 4.4 #9(b).  

Part 2: Next, write a complete proof for Croom Ch 4.4 #10.

Use a solid organizational structure:

– State the conclusions
– Clearly and precisely prove the conclusions from the hypotheses
– Results presented earlier in the text may be used and must be clearly documented
A few notes about format: use Microsoft Word; use Equation Editor for all mathematical symbols, e.g. x ∈ X or Cl(A) ⋂ Cl(X-A); and use the fonts Cambria and Cambria Math in size 11 so your typed work is the same font as your equations.
