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

Where LOA - parabola arc y2 = x from the point O (0, 0) to the point A (1, 1).

Where LABO - triangle with vertices A circuit (1, 0), B (0, 1), O (0, 0).

Where L - first coil helix x = acost, y = asint, z = at.

Where L - the upper half circle arc x2 + y2 = 2x in the positive direction bypass circuit.
