Hi,
I understand that you have an equation that you want to solve using the Newton-Raphson method but are facing an issue as you are not able to use the variable “k” from the previous iteration.
Without the actual code, it is difficult to suggest some solution upfront, but you can refer to the following documentation, which demonstrates how to implement the Newton-Raphson method.
As discussed in the above solution, “x_old” holds the final value from the previous iteration, so in a similar line of solution, you can also do the same for your equation.
I hope it helps!
