1) √3tg(x/3+п/3)= 3
tg(х/3 +π/3) = 3/√3
tg(x/3 +π/3) = √3
х/3 +π/3 = arctg√3+ πk , k∈Z
x/3 + π/3 =π/3 + πk, k ∈Z
x/3 = πk, k ∈ Z
x = 3πk , k ∈ Z
2) ctg(п/3-x/4)= 1
- Ctg(x/4 - π/3) = 1
Ctg(x/4 - π/3) = -1
x/4 - π/3 = arcCtg(-1) + πk , k ∈Z
x/4 - π/3 = 3π/4 + πk , k ∈ Z
x/4 = π + πk , k ∈ Z
x = 4π + 4πk , k ∈Z
