1. Solve the following tasks:
1.22 Find the height of a right circular cone least amount described Kolo sphere of radius R.

2. Find the general solution of (general integral) of the differential equation.
2.22 y = x5 / (x4 - 1)


3. Carry out a full investigation of these functions and build their schedules.
3.22 y = x3ex + 1
