Hi,

I have a question about derivatives of functions.

if i have the following function,

f <- function(x) x^3-2*x^2+3*x-5

i need a simple function for the derivative of this with respect to 'x', so that i can then sub in values to the the derivative function, and use Newtons method of finding a root for this.

Please help.

Regards,

Kon Knafelman
