1. The problem statement, all variables and given/known data The following sequence comes from the recursion formula for Newton's Method. x0= 1 , xn+1=xn-(tanxn-1)/sec2xn Show if the sequence converges or diverge. 2. Relevant equations 3. The attempt at a solution I don't really know where to start on this problem, I have tried to use some trig identities to no avail, but I don't know what else to do. Any help is appreciated, thanks!
