а) tgx = √3;

x = arctg(√3) + π * n, n ∈ Z;

x = π/3 + π * n, n ∈ Z;

b) tgx = - 1;

x = arctg(- 1) + π * n, n ∈ Z;

x = - arctg(1) + π * n, n ∈ Z;

x = - π/4 + π * n, n ∈ Z;

c) ctgx = - √3;

x = arcctg(- √3) + π * n, n ∈ Z;

x = - arcctg(√3) + π * n, n ∈ Z;

x = - π/6 + π * n, n ∈ Z;

d) ctgx = 1;

x = arcctg(1) + π * n, n ∈ Z;

x = π/4 + π * n, n ∈ Z;
