1. Calculate (up to two decimal places) the area of \u200b\u200bthe figure bounded by the above lines.
1.29 y = x + 1, y = cosx, y = 0
2. Calculate (up to two decimal places) the arc length of the line.
2.29 ? = 5 (1 + cos?)
3. Calculate (up to two decimal places) the volume of the body obtained by rotating the figure F around said axes.
3.29 F: y = x - x2, y = 0, Ox
4. Calculate (up to two decimal places) the surface area formed by the rotation of the arc of the curve L about said axis.
4.29 L: x = cost, y = 2 + sint, Ox
