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

Where LAB - ellipse arc x = cost, y = 2sint from point A (1, 0) to point B (0, 2)

Where L - cardioid curve ρ = 2 (1 + cosφ), 0 ≤ φ ≤ π / 2

Where L - x = arc curve t, y = 3 / √2t2, z = t3, 0 ≤ t ≤ 1.

Where LAB - arc of a parabola y = x2 from point A (1, 1) to point B (2, 4)
