Question:
Evaluate
$$\int_C \frac{\mathrm dz}{z^2 +4}$$
Along the line $x+y=1$ in the direction of increasing $x$.
There is no information about start point and end point.
How do i solve this?
If i want to parameterize this, i need some points for the lower and the upper bound in this integral. That's why i'm confused.
Please give me some hints, i don't need the "whole" answer. Thanks.
