I need some help with this question please. Thanks. : a) Let f: [0,1] [tex]\rightarrow R[/tex] be given by http://img148.imageshack.us/img148/5435/10187431tc4.gif [Broken] Argue that f is integerable. The attempt at a solution I don't get it. A function is integerable if its integral exists. How can we integrate this? There is no actual function given here... So how are we supposed to argue that it is integerable?
