Special purpose calculators: determine crown molding, find the bearing for a sundial (sun compass), face towards mecca, predict shadows, solve triangles (given angles or sides or ratios), apply Cramer's Rule, solve three equations with three unknowns (or four equations and four unknowns, or five ..., or six ...), solve for complex variables, apply the cubic formula, apply the quartic formula, calculate impedance, and arrange byeless schedules (e.g., for tournaments).
