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

Where LABC - the broken line ABC; A (1, 2); B (3, 2); C (3, 5)

Where LOA - a line segment connecting the points O (0, 0) and A (1, 2)

Where L - first arch cycloid x = a (t - sint), y = a (1 - cost).

Where L - arc sine wave y = sinx from point (π, 0) to the point (0, 0).
