Hi

In a 2013 exam, semester A moed B : regarding the Newton Raphson question number 1. The function is not derivable, yet for every selection of t, the result will be 1.5. One cannot use the Newton Raphson method on a non uniformly continuous function, so even for a selection of t from (-inf,2), (-2,0),(0,-2), (2,inf) - the result is still 1.5.

Yet, I dont feel comfortable with this answer because you cannot just use Newton Rapshon on any selection of t..

Is this correct ?

In addition to it, the lat question on a 2013 exam, semester A moed A - findSub time complexity.

given x,y - I use halves ("binary search") for x coordinate and halves for y coordinate - so I am not sure if the total time complexity is O(log(n))+O(log(n)) or is it O((log(n)**2) ?

thank you
