This worksheet introduces a Maple package, nurbs, which incorporates commands for the treatment of the most usual curves in CAGD (B-splines, Rationals B-splines, etc.). The powerful symbolic and graphical Maple capabilities, the functional and pattern recognition programming and the Maple visualization environment have been extensively applied to get a user-friendly, didactic and powerful tool for education, with applications in areas as CAGD and Computer Graphics. Some illustrative examples showing the performance of the package are also given. Dedicated to July Elizabeth, my wife.
