hi friends, i would like some help. How can i make a recorrence list like this: x[n+2]-s*x[n+1]+p*x[n]=0 with x[0]=2,x[1]=s output like this: [x[0],x[1],x[2],...] [2,s,s^2-2p,...] ... x[n+3]-a*x[n+2]+b*x[n+1]-c*x[n]=0 with x[0]=3,x[1]=s [x[0],x[1],x[2],...] ? .... i know that there's .... load(solve_rec); solve_rec... thanks.
