Solution for cos(18)=20/X equation: 


D( X )

X = 0

X = 0

X = 0

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

cos(18) = 20/X // - 20/X

cos(18)-(20/X) = 0

cos(18)-20*X^-1 = 0

-20*X^-1 = -cos(18) // : -20

X^-1 = cos(18)/20

-1 < 0

1/(X^1) = cos(18)/20 // * X^1

1 = (cos(18)/20)*X^1 // : cos(18)/20

20*(cos(18))^-1 = X^1

X = 20*(cos(18))^-1

X = 20*(cos(18))^-1
