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

Where L - the arc of the ellipse x = 3cost, y = 2sint with a positive traversal direction.

Where LAB - line segment contained between the points A (0, 4) and B (4, 0)

Where L - the first turn of the conical spiral line x = tcost, y = tsint, z = t.

Where LOA - arc of parabola z = x2 / 4 from the point O (0, 0, 0) to point A (2, 0, 1).
