A continuation from Add MS
f. of work on the equation arising from the multiplication .
Harriot states without proof the special form the equation will take when , when the term in vanishes. For a full derivation see Add MS 6783 f. (d.3). Harriot calls this form of the cubic equation an 'elliptic' or 'Bombellian' equation. The special case where he calls 'parabolic'. For Harriot's definitions of the hyperbolic, elliptic, and parabolic forms of a cubic equation without a square term, see Add MS 6783 f. (e.8).
On this page Harriot also gives the form the equation will take when , when the term in vanishes. For a full derivation see Add MS 6783 f. (d.3). ]
