Let f (z) = zi+ (z – 4).
Part (a)
Integrate the function f (z) along the curve C
t3+it? from z =1+ lito
given by z
z = 8+ 4i
Part (b)
Integrate the same function along the line from
O to 6i, then along the line from 6i to 6 + 6i,
then finally along the line from 6 + 6i to 0. Note
that you are evaluating the integral on a
triangular loop.
Part (c)
Integrate the function f (z) on the circle that
goes through 0, 6i, and 6 + 6i. Are the integrals
in Part (b) and Part (c) equal?
