A maths/dynamics question really for anyone who has tried doing rigid = body dynamics in a left handed world. I'm wondering what or if there is = a "usual" way to treat vector xproducts / Coriolis / and so on in a = left handed coordinate system. For eg., in no particluar order, a RHS has: 1 angles increase anticlockwise 2 e_i x e_j =3D e_k, for (i,j,k) any +ve perm of (1,2,3) and e_i,j,k the = usual unit direction vectors 3 Rdot =3D (omega*)R, ie epsilon_ijk.omega_j (R the orientation of the = body frame, omega the angular velocity vector, epsilon_ijk the = alternating tensor) 4 xdot_world =3D xdot_body + Cross(omega, x  cm_body) What happens to these in a LHS system to cope with computation of = angular quantities?
