Решите тригонометрические неравенства: 1) cos (x+п/5)» 1/2 2) tg (0,5-п/3)> из под корня 3/3

1)cos(x+π/5)≥1/2
-π/3+2πn≤x+π/5≤π/3+2πn,n∈Z
-8π/15+2πn≤x≤2π/15+2πn,n∈Z
x∈[-8π/15+2πn;2π/15+2πn,n∈Z]
2)tg(0,5x-π/3)>√3/3
π/6+πn<0,5x-π/3<π/2+πn,n∈Z
π/2+πn<0,5x<5π/6+πn
π+2πn<x<5π/3+2πn,n∈Z
x∈(π+2πn<x<5π/3+2πn,n∈Z)
