1. Calculate the data line integrals (1-4)

Where L - the circle x = 2cost, y = 2sint with a positive traversal direction.

Where LAB - section of the line AB; A (-1; 0); B (0, 1).

Where L - the arc of the curve x = acost, y = asint, z = bt, 0 ≤ t ≤ 2π.

Where L - x = arc curve Rcost, y = Rsint, z = at / (2π), «traversed" from its point of intersection with the plane z = 0 to the intersection of its plane with z = a.
