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

Where LAB - line segment AB, A (1, 1); B (3, 4).

Where LOB - parabola arc y2 = 2 / 3x between point O (0, 0) and B (√35 / 6, √35 / 3)

Where L - the first round of the lemniscate ρ2 = a2cos2φ.

Where L - quarter of the arc x = Rcost, y = Rsint, lying in the first quadrant, and "running" counter-clockwise.
