Solution for 4*cos((pi/6)x)=0 equation: 


x in (-oo:+oo)

4*cos((pi/6)*x) = 0

cos((pi/6)*x) = 0

cos((pi/6)*x) = 0  <=>  (pi/6)*x = pi*k_1+pi/2 i k_1 należy do I

t_1 = pi*k_1+pi/2

(pi/6)*x-t_1 = 0

(pi/6)*x-t_1 = 0 // + t_1

(pi/6)*x = t_1 // : pi/6

x = t_1/(pi/6)

x = pi*k_1+pi/2/(pi/6) i k_1 należy do I

4*cos((pi/6)*x) = 0  <=>  4 = 0 or 4*cos((pi/6)*x) = 0  <=>  cos((pi/6)*x) = 0

x = pi*k_1+pi/2/(pi/6)
