PROGRAMMING NEWTON RAPHSON ON PRIME

Hi

I need to use Newton algorythm with prime.

I write algorythm  step by step.

I don't know prime correctly  to make a program for iterative loop.

I need to make 10 loop max, and i want to program break when:

- iterative loop over 10

or

- Error control match with range value Ec

I need to enter manualy first step x0

I need to enter nanualy Error_control Ec

Please, can you help me to write NR with program in prime.

Thanks

find root for f(x) function with NR algorythm

Here's a slightly different function with two additional arguments - function and max.iterations - and a table as output:

Worksheet in P4 format attached.

    It's ok for me !!!

    Thanks!!!!

     

    For my use, it's not necessary to iterative loop is "var"

    ten value will be implemented in hard.

    But it's more pretty in your solutionSmiley Wink
