The question:

For the vector field = -y + x, find the line integral along the curve C from the origin along the x-axis to the point (6, 0) and then counterclockwise around the circumference of the circle x2 + y2 = 36 to the point \( (6)/sqrt(2), (6)/sqrt(2)\). Give an exact answer.

i think from x=0 to x=6 it is 0 but how do i get the second part? help please
