Solution for Cos(pi/x) equation: 


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

cos(pi/x) = 0

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

t_1 = pi*k_1+pi/2

pi/x-t_1 = 0

pi*x^-1 = t_1 // : pi

x^-1 = t_1/pi

-1 < 0

1/(x^1) = t_1/pi // * x^1

1 = (t_1/pi)*x^1 // : t_1/pi

1/(t_1/pi) = x^1

x = 1/(t_1/pi)

x = 1/(pi*k_1+pi/2/pi) i k_1 należy do I

x = 1/(pi*k_1+pi/2/pi)
