Quite surprised if it isn't the same procedure... on the 85/86's you can use
nDer(, der1( or der2(, where the last two are the most precise however
Der( can find n'th numerical derivative.
The syntax for der1( is der1(expression,variable,value)
For instance you would use der1(ln(3-x^2),x,1) to find the derivative of
ln(3-x^2) in the point where x=1.
