Thanks Oscar for the video! Would you be able to explain (or link to resources that explain) why |g'(x)|<1 predicts convergence?

Wish I found your channel earlier man.

Your last video about finding roots come form 7 years ago it is a very very very late answer
what was going on for this 7 years? cast away?

I think you still did not answer the first part of the last question, what is the point of this method if the root is already known, as we need it to test convergence ?

Hey, Is all this convergence or divergence totally depend upon intial guess ?

Is it fair to say that if youre initial guess x0 is inside of the region where |g'(x)|<1 that it will converge to an x* in that range, if one exists?

''Find the approximate value of 3^(3/4) with the fixed point ''... How can I find the g(x) if I can't use my calculator? to put the real vAlue
