Solution for cos(x-pi/4) equation: 


x in (-oo:+oo)

cos(x-(pi/4)) = 0

cos(x-(pi/4)) = 0  <=>  x-(pi/4) = pi*k_1+pi/2 i k_1 należy do I

t_1 = pi*k_1+pi/2

x-t_1-(pi/4) = 0

x-t_1-(pi/4) = 0 // + -t_1-(pi/4)

x = -(-t_1-(pi/4))

x = t_1+pi/4

x = pi*k_1+pi/2+pi/4 i k_1 należy do I

x = pi*k_1+pi/2+pi/4
