Solution for k-212/k equation: 


D( k )

k = 0

k = 0

k = 0

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

k-(212/k) = 0

k-212*k^-1 = 0

1*k^1-212*k^-1 = 0

(1*k^2-212*k^0)/(k^1) = 0 // * k^2

k^1*(1*k^2-212*k^0) = 0

k^1

k^2-212 = 0

k^2-212 = 0

DELTA = 0^2-(-212*1*4)

DELTA = 848

DELTA > 0

k = (848^(1/2)+0)/(1*2) or k = (0-848^(1/2))/(1*2)

k = 2*53^(1/2) or k = -2*53^(1/2)

k in { -2*53^(1/2), 2*53^(1/2)} 

k in { -2*53^(1/2), 2*53^(1/2) }
