Best ResponseYou've already chosen the best response.0i know its where you guess half way and then see if the answer is lower or higher. I'm just now super clear on how to set it up in python

Best ResponseYou've already chosen the best response.2You should write a psudo code first x is the value you are searching a is the max range b is the min range c is (a+b)/2 > midpoint if x>c: the min range will be c now. else: the max range will be c now Something like that :) try working around it

Best ResponseYou've already chosen the best response.0Are you referring specifically to Newton's method? Because that actually has a rather complicated proof to explain why it converges on the square root. For just how to implement it in Python, review the code from Prof. Guttag's examples: http://ocw.mit.edu/courses/electricalengineeringandcomputerscience/600scintroductiontocomputerscienceandprogrammingspring2011/unit1/lecture3problemsolving/MIT6_00SCS11_lec03.pdf
