Solution for -n^(-1/2)+6=11/2 equation: 


D( n )

-n = 0

-n < 0

-n = 0

n = 0

-n < 0

n in (0:+oo)

(-n)^(-1/2)+6 = 11/2 // - 11/2

(-n)^(-1/2)-(11/2)+6 = 0

(-n)^(-1/2)-11/2+6 = 0

(-1)^(-1/2)*n^(-1/2) = -1/2 // : (-1)^(-1/2)

n^(-1/2) = -1/2/((-1)^(-1/2))

-1/2 < 0

1/(n^(1/2)) = -1/2/((-1)^(-1/2)) // * n^(1/2)

1 = (-1/2/((-1)^(-1/2)))*n^(1/2) // : -1/2/((-1)^(-1/2))

1/(-1/2/((-1)^(-1/2))) = n^(1/2)

n^(1/2) = 1/(-1/2/((-1)^(-1/2))) // ^ 2

n = -4

n in { -4} 

n belongs to the empty set
