I have a set of four functions which are related by a series of recursive formulae. For example (The real problem is a much messier version of this), b[n+1]-b[n-1]=b[n] b[n+1]*sin((n+1)/2*pi) -d[n-1]*sin((n-1)/2*pi) +c[n+1]*sin((n+1)/2*pi) -e[n-1]*sin((n-1)/2*pi) = d[n]*sin(n/2*pi) - e [n]*sin(n/2*pi) b[n+1]*sin(3(n+1)/2*pi) -d[n-1]*sin(3(n-1)/2*pi) +c[n+1]*sin(3(n+1)/2*pi) -e[n-1]*sin(3(n-1)/2*pi) = d[n]*sin(3n/2*pi) - e [n]*sin(3n/2*pi) Well, I actually have more terms and a bigger mess, but can I use mathematica to untangle this mess like this? -- Rudolph J.
