1. Solve the following tasks:
1.1 Linen tent volume V is in the form of direct cone. What should be the ratio of the height of the cone to the radius of its base to the tent went to the least amount of fabric?

2. Carry out a full investigation of these functions and build their schedules.
2.1 y = (x2 - 2x +2) / (x - 1)

3. Carry out a full investigation of these functions and build their schedules.
3.1 y = e2x -x2

4. Find the minimum and maximum values of the function y = f (x) on the interval [a; b]
4.1 y = ln (x2 - 2x + 2), [0; 3]
