Abstract
We present a new proof that aq-step backward difference scheme for the approximate solution of a first order ordinary differential equation is stable in the sense of Dahlquist iff 1≦q≦6.
The only other proof known to the authors was given by Cryer in a condensed version with most proofs omitted of a much larger technical report.
