Solution for tan(1.5/x) equation: 


D( x )

x = 0

cos(1.5/x) = 0

x = 0

x = 0

cos(1.5/x) = 0

cos(1.5/x) = 0

cos(1.5/x) = 0  <=>  1.5/x = pi*k_1+pi/2 i k_1 należy do I

t_1 = pi*k_1+pi/2

1.5/x-t_1 = 0

1.5*x^-1 = t_1 // : 1.5

x^-1 = 0.66666667*t_1

-1 < 0

1/(x^1) = 0.66666667*t_1 // * x^1

1 = 0.66666667*t_1*x^1 // : 0.66666667*t_1

1.49999999*t_1^-1 = x^1

x = 1.49999999*t_1^-1

x = 1.49999999*pi*k_1+pi/2^-1 i k_1 należy do I

x in {( -oo : +oo ) / {< 0 : 0 > U < 1.49999999*pi*k_1+pi/2^-1 : 1.49999999*pi*k_1+pi/2^-1 >}} i k_1 -> {I}

tan(1.5/x) = 0

tan(1.5/x) = 0  <=>  1.5/x = pi*k_1 i k_1 należy do I

t_1 = pi*k_1

1.5/x-t_1 = 0

1.5*x^-1 = t_1 // : 1.5

x^-1 = 0.66666667*t_1

-1 < 0

1/(x^1) = 0.66666667*t_1 // * x^1

1 = 0.66666667*t_1*x^1 // : 0.66666667*t_1

1.49999999*t_1^-1 = x^1

x = 1.49999999*t_1^-1

x = 1.49999999*pi*k_1^-1 i k_1 należy do I

x = 1.49999999*pi*k_1^-1
