The fundamental equation for correct steering is (where φ and α = Angle through which the axis of the outer wheel and inner wheel turns respectively, c = Distance between the pivots of the front axles, and d = Wheel base)

tanφ + cotα = b/c

cosφ - sinα = c/b

cotφ - cotα = c/b

sinφ + sinα = b/c

tanφ + cotα = b/c

cosφ - sinα = c/b

cotφ - cotα = c/b

sinφ + sinα = b/c
