Autograph uniquely allows ODEs to be entered implicitly, allowing a

well structured approached to evolve from 1st order to 2nd order,

including hhe idea of ''complimentary function'' and ''particular

integral''. Solution sets can be treated as dynamic objects.

Vectors can likewise be taught from first principles in 2D, leading

to a firm understanding of their use in 3D.
