Solution for cos(55)=(16/x) equation: 


D( x )

x = 0

x = 0

x = 0

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

cos(55) = 16/x // - 16/x

cos(55)-(16/x) = 0

cos(55)-16*x^-1 = 0

-16*x^-1 = -cos(55) // : -16

x^-1 = cos(55)/16

-1 < 0

1/(x^1) = cos(55)/16 // * x^1

1 = (cos(55)/16)*x^1 // : cos(55)/16

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

x = 16*(cos(55))^-1

x = 16*(cos(55))^-1
