The Diophantine equation X(X+1)(X+2)(X+3)=14Y(Y+1)(Y+2)(Y+3) still remains open.Using recurrence sequence,Maple software,Pell equation and quadraric residue,thi
In order to get an approximation with better effect of parameterization of Bézier curves,we proposed a method for arc-length parameterization and the corre
