Integrallash usullari

> implicitplot(y=2*(1/x-1/(x^2)), x=0..6, y=-1..1,color= blue, thickness=2);

2)jisim xajmini 2 xil usulda hisoblaymiz.
a) formula bo`yicha:
> XI4:=4*Pi*Int((1/x-1/(x^2))^2,x=1..infinity);

> XI4:=4*Pi*int((1/x-1/(x^2))^2,x=1..infinity);
b) VolumeOfRevolution buyrug`i bo`yicha jisim xajmini [1,6] dagi qismi:
> restart; with(plots): with(Student[Calculus1]):
> VolumeOfRevolution((x-1)/x^2,x=1..6,output=plot);

> VolumeOfRevolution(2*(x-1)/x^2,x=1..6, output=integral);

> value(%);
