As Newton-Raphson is essentially numeric there is little point in using a symbolic equals.  Just stick with numerics.

Here is my equivalent using Mathcad 8 Express:

As Alan I am asking what the idea of a symbolical evaluation of the intermediate results of a numerical approximation algorithm might be!!

Whats wrong with

Here is the (unsimplified) symbolic result with four iteration steps.

Are you sure that you really want to see the result for 5 or more steps? 🙂

Using "simplify" or "simplify, max" may give you a more compact result at the cost of a lot of coffee to drink while  waiting for the calculation to finish.

But again, what's the sense of displaying those results symbolically?

If you really need to see the symbolic representation of the fifth iteration step, here it is

And for an exact symbolic result

So, Thank you all for your comments and vigilance. It's fine and enough in this case to display results in numerical form.
Thank you.
