Solution for cos(55)=4/x equation: 


D( x )

x = 0

x = 0

x = 0

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

cos(55) = 4/x // - 4/x

cos(55)-(4/x) = 0

cos(55)-4*x^-1 = 0

-4*x^-1 = -cos(55) // : -4

x^-1 = cos(55)/4

-1 < 0

1/(x^1) = cos(55)/4 // * x^1

1 = (cos(55)/4)*x^1 // : cos(55)/4

4*(cos(55))^-1 = x^1

x = 4*(cos(55))^-1

x = 4*(cos(55))^-1
