Define
p = graph G is bipartite
(a) Represent the following statements symbolically using the statement vari-
ables given above. Do not simplify your answers.
i. Graph G is bipartite if and only if it has only cycles of even length.
q=graph G has only cycles of even length
ii. Graph G being bipartite is a necessary condition for G only having
cycles of even length, and G being bipartitie is a sufficient condition
for G only having cycles of even length.
(b) Show that the statement given in part (i) is logically equivalent to the
statement given in part (ii) using methods from class.
(c) Negate the statement given in part (ii).

(d) Use part (c) to give a rule for negating an if and only if statement. That
is, find a rule for ~ (pq). Justify.
(e) We know that either a statement or its negation is true. Investigate, using
the internet or graph theory textbooks, whether the statements from part
(a) or their negations are true. Cite your sources.
