In Newton's method (or family of methods that look as such), you need a derivative. You have at least three choices. You can take the derivative at the solution (at x=2). In general this doesn't work...

I am worried you have utterly confused yourself by attempting to understand a transient problem and transient solver without fully grasping the more basic steady problem and steady solver first. ...

No, you get a system like 3x=6. The solution is just 2. If you actually do carry out the discretization for the simple heat equation with constant material properties etc. (this is a good...

There are true steady state solvers where there is no concept of time. Question is whether you have a true steady solver or whether you have a transient solver in disguise. Even if there...

The difference between explicit and implicit time-stepping as you already know is whether you are doing purely arithmetic or solving a system of equations. Although I'm about to spoil the beans,...
