## Integral Calculus

The oriented and the absolute content of the area between two function curves in a desired interval,
i.e. the two integrals, are calculated

Also are determined:

- the twisting moments for rotation around x-, respectively y-axis,
- the bodies of revolution covered, and
- the centroid of the area

### Example:

f1(x)=4-x^2 , f2(x)=(x-1)^2
interval from 0 to 1.5
oriented and absolute Content A1 = A2 = 4.5
twisting moments Mx=8.1563 My=3.0938
bodies of revolution Vx=51.247 Vy=19.439
centroid S(0.6875/1.8125)
