Vamos a resolver la ecuacion diferenical con Sagemath:
Sage: var('x A') Sage: z=function('z',x) Sage: f1(x)=+x^3*diff(z,x)-x^2*z-4*A*x*x*z+2*x+diff(z,x) Sage: f2=desolve(f1(x)==0,z,ivar=x,contrib_ode=True) Sage: f3=A*x+1/f2 Sage: f3 Resultado de Sagemath A*x + e^(-1/3*(4*A + 1)*log(x^2 - x + 1) - 1/3*(4*A + 1)*log(x + 1))/(c - 2*integrate(x*e^(-1/3*(4*A + 1)*log(x^2 - x + 1) - 1/3*(4*A + 1)*log(x + 1))/(x^3 + 1), x))
