Question

\[\int\limits_{C}^{}\] dz/z



where c consists of three line segments:
From z = 1 to z = 1-i
From z = 1-i to z = -1-i
From z = -1-i to z = -1

Answer 1

dz/z ints to ln(z)

then apply your limits 3 times is what im thinking

Answer 2

how about boundaries

Answer 3

im not sure i can decipher that for boundaries tho ....

Answer 4

and if we are in complex plane, i cant say im confident enough to play with it :/
