Solution for Cos(23)=4/x equation: 


D( x )

x = 0

x = 0

x = 0

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

cos(23) = 4/x // - 4/x

cos(23)-(4/x) = 0

cos(23)-4*x^-1 = 0

-4*x^-1 = -cos(23) // : -4

x^-1 = cos(23)/4

-1 < 0

1/(x^1) = cos(23)/4 // * x^1

1 = (cos(23)/4)*x^1 // : cos(23)/4

4*(cos(23))^-1 = x^1

x = 4*(cos(23))^-1

x = 4*(cos(23))^-1
