This question popped up in my head. What is sin x when x tends to infinity? Since sine is a preiodic functions which repeats itself, is the answer 1, -1 or 0 or something else altogether?
What's wrong with [itex]\geq[/itex]? You want to show that [itex]\|f(x)-f(x_0)\|<\epsilon[/itex] does not hold for all [itex]x>x_0[/itex], so you find an [itex]x[/itex] where the relation is [itex]\geq[/itex] instead of [itex]<[/itex].dextercioby said:It looks good to me until [itex]\geq[/itex].
