Solution for (w/5)-(5/w) equation: 


D( w )

w = 0

w = 0

w = 0

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

w/5-(5/w) = 0

w/5-5*w^-1 = 0

1/5*w^1-5*w^-1 = 0

(1/5*w^2-5*w^0)/(w^1) = 0 // * w^2

w^1*(1/5*w^2-5*w^0) = 0

w^1

(1/5)*w^2-5 = 0

(1/5)*w^2-5 = 0

DELTA = 0^2-(-5*4*(1/5))

DELTA = 4

DELTA > 0

w = (4^(1/2)+0)/(2*(1/5)) or w = (0-4^(1/2))/(2*(1/5))

w = 5 or w = -5

w in { -5, 5} 

w in { -5, 5 }
