Cos(2x/3+π/4)=1/√2
cos(2x/3+π/4)=√2/2
2x/3+π/4= + - π/4 + 2πn, n∈Z
1) 2x/3 +π/4 = π/4 + 2πn, n∈Z
2x/3 = π/4 - π/4 + 2πn
2x/3 = 2πn
x= (3/2) * 2πn
x= 3πn, n∈Z
2) 2x/3 +π/4 = -π/4 +2πn, n∈Z
2x/3 = -π/4 - π/4 + 2πn
2x/3 = -π/2 + 2πn
x= (3/2) *(-π/2) + (3/2)*(2πn)
x= -3π/4 + 3πn, n∈Z
Ответ: -3π/4 + 3πn, n∈Z;
3πn, n∈Z.

Cos(2x/3+π/4)=1/√2cos(2x/3+π/4)=√2/2
2x/3+π/4= + - π/4 + 2πn, n∈Z
1) 2x/3 +π/4 = π/4 + 2πn, n∈Z
2x/3 = π/4 - π/4 + 2πn
2x/3 = 2πn
x= (3/2) * 2πn
x= 3πn, n∈Z
2) 2x/3 +π/4 = -π/4 +2πn, n∈Z
2x/3 = -π/4 - π/4 + 2πn
2x/3 = -π/2 + 2πn
x= (3/2) *(-π/2) + (3/2)*(2πn)
x= -3π/4 + 3πn, n∈Z
Ответ: -3π/4 + 3πn, n∈Z;
3πn, n∈Z.
