QUIZ 7.3
1. To show that converges, it is sufficient to show that P.V. converges. (a) True ; (b) False .
2. If f is an odd function and P.V. exists, then must converge. (a) True ; (b) False .
3. converges. (a) True ; (b) False .
4. To evaluate as an integral f(z)dz, we use the substitution z = exp(i). (a) True ; (b) False .
Notes
converges, it is sufficient to show that P.V.
converges.
as an integral 
f(z)dz, we use the substitution z = exp(i
).
