x in (-oo:+oo)
(1/4)*sin(4*x) = 0
1/4 = 0
1/4 = 0
x belongs to the empty set
sin(4*x) = 0
sin(4*x) = 0 <=> 4*x = pi*k_1 i k_1 należy do I
t_1 = pi*k_1
4*x-t_1 = 0
4*x-t_1 = 0 // + t_1
4*x = t_1 // : 4
x = t_1/4
x = pi*k_1/4 i k_1 należy do I
(1/4)*sin(4*x) = 0 <=> 1/4 = 0 or (1/4)*sin(4*x) = 0 <=> sin(4*x) = 0
x = pi*k_1/4
