Solution for 3m/m^3+7/2m equation: 


D( m )

m^3 = 0

m^3 = 0

m^3 = 0

1*m^3 = 0 // : 1

m^3 = 0

m = 0

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

(7/2)*m+(3*m)/(m^3) = 0

7/2*m+3*m^-2 = 0

m*(3*m^-3+7/2) = 0

3*m^-3 = -7/2 // : 3

m^-3 = -7/6

-3 < 0

1/(m^3) = -7/6 // * m^3

1 = -7/6*m^3 // : -7/6

-6/7 = m^3

m^3 = -6/7 // ^ 1/3

m = -(6/7)^(1/3)

m = 0

m = 0

m in { 0} 

m = -(6/7)^(1/3)
