Solution for sin(2x)(3.14/4) equation: 


x in (-oo:+oo)

(3.14/4)*sin(2*x) = 0

3.14/4 = 0

0.785 = 0

x belongs to the empty set

sin(2*x) = 0

sin(2*x) = 0  <=>  2*x = pi*k_1 i k_1 należy do I

t_1 = pi*k_1

2*x-t_1 = 0

2*x-t_1 = 0 // + t_1

2*x = t_1 // : 2

x = t_1/2

x = pi*k_1/2 i k_1 należy do I

(3.14/4)*sin(2*x) = 0  <=>  3.14/4 = 0 or (3.14/4)*sin(2*x) = 0  <=>  sin(2*x) = 0

x = pi*k_1/2
