A simple relation has been evolved for the analytical evaluation of indenter orientation dependent variables in Brooke's formula for the effective resolved shear stress (ERSS) on a slip system of a crystal produced by a hardness indenter. Its merits over the stereographic method are considered. In association with this the hardness anisotropy of InBi1-xSex and InBi1-xSbx single crystals has been studied and the analysis shows that minimum values of hardness are obtained. The rotation of indenter with respect to its initial setting with maximum values in between them and the results are discussed in details.
