Solution for b^-2=1/2 equation: 


D( b )

b = 0

b = 0

b = 0

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

b^-2 = 1/2 // - 1/2

b^-2-(1/2) = 0

b^-2-1/2 = 0

1*b^-2 = 1/2 // : 1

b^-2 = 1/2

-2 < 0

1/(b^2) = 1/2 // * b^2

1 = 1/2*b^2 // : 1/2

2 = b^2

b^2 = 2 // ^ 1/2

abs(b) = 2^(1/2)

b = 2^(1/2) or b = -2^(1/2)

b in { 2^(1/2), -2^(1/2) }
