Answer 2

Ответ:

6arccos(x)²-1(44piarccos(x))+14pi²=0

6arccos(x)²-44(piarccos(x)+14pi²=0

2(3arccos(x)²-22piarccos(x)+7pi²)

3arccos(x)²-22piarccos(x)+7pi²=0

(pi-3arccos(x))(7pi-arccos(x))

2(pi-3arccos(x))(7pi-arccos(x))

-1<=1/2=[]

[]

6arccos(1/2)²-44piarccos(1/2)+14pi²=0

0=0

x=1/2=[]

[]

x=1/2
