[comp.sys.handhelds] Looking for a math program: Read and see...

I am looking for a math program for the HP48 that will do things that includes 
the following:

 I have a function in the format of :F(Vin,Vout)=const

 I need to find when  (dVout/dVin)=-1 .
  That is, for what (Vin,Vout) both equations will be right.
 Other parameters may be numbers only, but would be better if parametric solutions will also be available...

 Thanks
