Sin(p/2-8x)=cos(8x)
1-cos(8x)-sin(4x)=0
cos(8x)= ( (cos4x)^2-(sin4x)^2 )
1-
(cos4x)^2 + (sin4x)^2) -sin4x=0
1-(cos4x)^2=(sin4x)^2
(sin4x)^2+
(sin4x)^2-sin4x=0
2*(sin4x)^2-
(sin4x)=0
(sin4x)=t
2*t^2-t=0
t(2t-1)=0
t=0
t=1/2
1)sin4x=0 2)sin4x=1/2
1)4x=Пn
x=Пn/4
2)4x=П/6+2пn х=П/24+пn/2
4x=5п/6+2пn x=5П/24+пn/2

1-cos(8x)-sin(4x)=0
cos(8x)= ( (cos4x)^2-(sin4x)^2 )
1-(cos4x)^2 + (sin4x)^2) -sin4x=0
1-(cos4x)^2=(sin4x)^2
(sin4x)^2+(sin4x)^2-sin4x=0
2*(sin4x)^2-(sin4x)=0
(sin4x)=t
2*t^2-t=0
t(2t-1)=0
t=0
