Theory of Machine
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)

cosφ - sinα = c/b
sinφ + sinα = b/c
tanφ + cotα = b/c
cotφ - cotα = c/b
