Given the following equations: v = w**2 - p x = v**2 - p y = x**2 - p z = y**2 - p I re-write them as Macsyma "expressions": e1: v - w**2 + p e2: x - v**2 + p e3: y - x**2 + p e4: z - y**2 + p In Macsyma, I invoke "eliminate([e1,e2],[v])" which yields an expression, say e5, involving x, w, and p. Similarly, I invoke "eliminate([e3,e4],[y]" which yields an expression, say e6, involving x, z, and p. NOW: When I try to invoke "eliminate" on e5 and e6 to eliminate x, it returns the list [1]. Why?
