Solution of an ordinary differential equation (O.D.E.)
Fix the value of Nmax, positive integer. That value defines the order (less than Nmax) of a polynomial solution :
Fix Smax, positive integer. That value defines the number of terms in a series solution :
Fix Argstop, positive integer less than or equal to Nmax:
Choose the name of the unknown :
Choose the name of the independant variable :
Enter the equation to solve (Reduce syntax) :
y*df(y,x,2)-df(y,x)**2+f*y*df(y,x)+g*y**2=0
If the equation contains arbitrary functions (of the independant variable), type them here (ex: p,q,r) :
If you know a particular solution of the equation without second side, type it here (ex: y=sin(x)) otherwise skip this field :
Click here if a parametric solution would satisfy you?
