The sequence given by the iteration formula:
Xn+1 = arccos(-1/Xn) with Xo=2.5 converges to α
(i) Show that α is the x-coordinate of a stationary point of C.
I'm entirely baffled by this question. I was told I need to let n tend to infinity then I'll get an equation involving alpha but I'm very confused how to even start this.
Any help is vastly appreciated!
