Hi,
I wrote a simple derivative program
(ftest=deriv(y~x^2, c("x"), function(x){} ))
I put (ftest=deriv(y~x^2, c("x"), function(x){} ))(1) which return 2 which
is correct.
however, if I want the output to be 0 and hopefully a new inverse function
can take in
output (2) and return x=1. Can this be accomplished. Maybe output(0) can
return x=0
Thanks
pat
