# the reciprocal of a Simple Hexagonal Bravais lattice with lattice constants a , b , and c (|a|=|b| = a, and |c|=c ) and ==90 and = 120 is another

the reciprocal of a Simple Hexagonal Bravais lattice with lattice constants **a**, **b**, and **c** (|a|=|b| =a, and |c|=c ) and α=β=90˚ and **γ** = 120˚ is another Simple Hexagonal lattice with lattice constants **a***, **b***, and **c* **where** |c*|** =c* 1/c and |a*| = |b*|=a* , and wherein α*=β*=90˚ and **γ*** = 60˚, and** a*** is oriented at an angle of 30˚ with respect to **a**, **b*** is perpendicular to **a**, and **c* **is parallel to** c **while both **c** and **c*** are perpendicular to** a**, **b**, ** a***, and **b***,

Calculate **a**, **b**, **c**, **a***, **b*** and **c*** on an (001) stereographic projection
