Let $C [a,b]$ be a set of all real-valued functions $x(t),y(t),...$ which are functions of an independent real variable $t$ and are defined and continuous on a closed interval $[a,b]$. Show that $C [a,b]$ is a Banach space with norm given by
$||x|| = max_{t∈[a,b]}|x(t)|$.

Can you at least verify that it is a vector space, and that the norm given actually qualifies as one? This should be straightforward verification of the definitions. If you have any confusion, please mention it above.

Another fact you have probably already seen: the uniform limit of a sequence of continuous functions is continuous.
