Quartic
2D/3D

Quartic is a setting for the FitDegree option for SolveFree and SolvePath. Quartic specifies a quartic approximation of each section of the integrand.

Quartic is generally more accurate than Cubic, but slower.
Quartic uses quartic interpolation for the predictor step, and quintic interpolation for the corrector step.
