Solution for cos(3x/2) equation: 


x in (-oo:+oo)

cos((3*x)/2) = 0

cos((3*x)/2) = 0  <=>  (3*x)/2 = pi*k_1+pi/2 i k_1 naleu017Cy do I

t_1 = pi*k_1+pi/2

(3*x)/2-t_1 = 0

3/2*x-t_1 = 0 // + t_1

3/2*x = t_1 // : 3/2

x = t_1/3/2

x = 2/3*t_1

x = 2/3*pi*k_1+pi/2 i k_1 naleu017Cy do I

x = 2/3*pi*k_1+pi/2
