Solution for Sin(3t-(pi/2)) equation: 


t in (-oo:+oo)

sin(3*t-(pi/2)) = 0

sin(3*t-(pi/2)) = 0  <=>  3*t-(pi/2) = pi*k_1 i k_1 należy do I

t_1 = pi*k_1

3*t-t_1-(pi/2) = 0

3*t-t_1-(pi/2) = 0 // + -t_1-(pi/2)

3*t = -(-t_1-(pi/2)) // : 3

t = (-(-t_1-(pi/2)))/3

t = (t_1+pi/2)/3

t = (pi*k_1+pi/2)/3 i k_1 należy do I

t = (pi*k_1+pi/2)/3
