We show that, at the one loop level, the \underline{slopes} of a number of observable quantities in an energy region around 3 TeV are only dependent on $\tanβ$. Under optimal experimental conditions, a combined measurement of slopes might identify $\tanβ$ values in a range $\tanβ< 2$, $\tanβ>20$ with acceptable precision.14 pages, 6 Encapsulated PostScript figuresHigh Energy Physics - Phenomenologytext
