Помогите!!!!!!!!!!!!!!!!!!!!!!!!!!! Очень, очень срочно!!!!!!!! Лайк и т.п. !!!!!!!!

1 sin(x-π/3)=-1 x-π/3=-π/2+2πn x=-π/6+2πn,n∈z 2 tg(π/6-x)=-1/√3 tg(x-π/6)=1/√3 x-π/6=π/6+πn x=π/3+πn,n∈z 3 cosx=a 2a²+5a+2=0 D=25-16=9 a1=(-5-3)/4=-2⇒cosx=-2<-1 нет решения a2=(-5+3)/4=-1/2⇒cosx=-1/2⇒x=+-2π/3+2πn,n∈z 4 2cos2xcosx=0 U sinx≠-1⇒x≠-π/2+2πn,n∈z cos2x=0⇒2x=π/2+πn⇒x=π/4+πn/2,n∈z cosx=0⇒x=π/2+πk,k∈z с учетом ОДЗ x=π/2+2πk,k∈z 5 sinx>-√3/2 x∈(-π/3+2πn;4π/3+2πn,n∈z) 6 tg(π/3-x)≤1/√3 tg(x-π/3)≥-1/√3 -π/6+πn≤x-π/3<π/2+πn π/6+πn≤x<5π/6+πn x∈[π/6+πn;5π/6+πn,n∈z)
