Quella che all’apparenza sembra un innocua equazione di quarto ordine putroppo mi ha presentato alcune brutte sorprese…

Ovvero
-1/4*(2*a*b-2*a1*b+2*a1*b1-2*a*b1)/
(-2*a1*a+a1^2+a^2)+1/2/(a-a1)*
(2*m1*m-m1^2-m^2)^(1/2)+1/2/(a-a1)*
(-(4*a*(-(-m1+m)^2)^(1/2)*c+4*a*m1*q1-4*a*m*q1-4*a*m1*q+4*a*m*q-4*a*
(-(-m1+m)^2)^(1/2)*c1+4*b*m1*m+4*m*q1*a1-4*(-(-m1+m)^2)^(1/2)*
c*a1-4*m1*q1*a1-4*b1*m1*m+(-(-m1+m)^2)^(1/2)*m1^2+4*(-(-m1+m)^2)^
(1/2)*a1*c1-2*b*m1^2-(-(-m1+m)^2)^(1/2)*b1^2+2*b1*m1^2-4*m*q*a1-
(-(-m1+m)^2)^(1/2)*b^2+2*(-(-m1+m)^2)^(1/2)*b*b1+2*b1*m^2+(-(-m1+m)^2)^
(1/2)*m^2-2*b*m^2-2*(-(-m1+m)^2)^(1/2)*m1*m+4*m1*q*a1)/(-(-m1+m)^2)^
(1/2))^(1/2)
(continua…)
