here's the thing :
I've been trying to solve an equation involving an interpolating function " y[x]==0 " (y[x] being the interpolating function) .
I tried to use NSolve but it doesn't work... (NSolve[y[s]==0 /. soluce[[1,3]],s]).
Mathematica returns me an error message about the "InverseFunction"...
Sine I'm a beginner with mathematica and got no help around me, can someone tell me how to do ?
thanx a lot.
