hello Group,
I want to find the parameter of the spline function @ x=.9 in order to 
find the appropriate value of y?
I can eye ball it using Table [{t,f[t]},{t,0,1,.01}] but I would like to 
get it straihgt...
Also I would like to know what is the appropriate Spline-degree I should 
use?
thnks in advance,
Eric

pts={{0.3, 0.74152}, {0.4, 0.650256}, {0.5, 0.588225}, {0.6,
   0.541167}, {0.8, 0.473432}, {1., 0.425661}, {1.022, 0.42067}, {1.25,
    0.380029}, {1.5, 0.346518}, {2., 0.300173}, {2.044, 0.297321}};
f= BSplineFunction[pts,SplineDegree->5];

f[?]={0.9,?}
