Hi

I recently have been trying to solve this problem, which I had on an exam however I can't seem to get it right the problem is as follows:

The main problem I am having is that i don't know how to solve for the Required Precision and the Stability.

I know that the actual precision is = 1/2^(N+1) but i don't know the formulae for "required precision" or "stability".

Please help....the question with my attempt is attached in jpg format below.

Hi Bertus,

Thank you alot for the posts but it still doesn't answer any of my questions about the Precision and Stability.

From what I understand there are set formulae for these, the tutorials just explain what the dual slope does, it doesnt talk about precision or stability............

Thank you but i'm still stuck
