So the integral is along the straight line segment from 1 to i. I parameterized the curve as , defined as and then used the property that dividing 1 by z is the equivalent of . So I have (with the constant (-1+i) omitted):
I have no clue how to integrate these... is there some trick I'm forgetting? any help?
