The following functions should work for the n-derivative (N) of' a function defines in an implisit equation (eqq) with repsect to the independent variable (var1) and the dependent variable (var2).
Note the program impdif(eq,varx,vary) is a standalone function
as is called by impdif(eqq,var1,var2,n).

Good Luck

Gary Wardall

impdif(eqq,var1,var2,n)
Func
Local v,i,yp
impdif(eqq,var1,var2)/->/yp
d(yp,var1)+d(yp,var2)*yp
yp/->/v
For i,2,n,1
d(v,var1)+d(v,var2)*v/->/v
EndFor
EndFunc

***************

impdif(eq,varx,vary)
d(right(eq)-left(eq),varx)/(d(left(eq)-right(eq),vary))
