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

Where LAB - section of the line AB; A (1, 0); B (0, 2).

Where LAB - astroid curve x = cos3t, y = sin3t between points A (1, 0) and B (0, 1)

Where L - the arc of a parabola y2 = 6x, severed parabola x2 = 6y.

Where L - triangle circuit with vertices A (0, 0), B (1, 0), C (0, 1) with the positive direction of the bypass circuit.
