(5/2)*sin((2/3)*x-(3.14/3)) = 0
(5/2)*sin((2/3)*x-1.04666667) = 0
5/2 = 0
5/2 = 0 // * 2
5 = 0
sin((2/3)*x-(3.14/3)) = 0
sin((2/3)*x-1.04666667) = 0
sin((2/3)*x-(3.14/3)) = 0 <=> (2/3)*x-(3.14/3) = pi*k_1 i k_1 należy do I
t_1 = pi*k_1
(2/3)*x-t_1-(3.14/3) = 0
(2/3)*x-t_1-1.04666667 = 0
2/3*x-t_1-1.04666667 = 0 // + -t_1-1.04666667
2/3*x = -(-t_1-1.04666667) // : 2/3
x = (-(-t_1-1.04666667))/2/3
x = 3/2*(t_1+1.04666667)
x = 3/2*(pi*k_1+1.04666667) i k_1 należy do I
(5/2)*sin((2/3)*x-(3.14/3)) = 0 <=> 5/2 = 0 or (5/2)*sin((2/3)*x-(3.14/3)) = 0 <=> sin((2/3)*x-(3.14/3)) = 0
x = 3/2*(pi*k_1+1.04666667)
