Effortlessly split PDFs with just a few mouse clicks

View file properties like length, read-only status, producer, date of creation and last modification, as well as unlock the PDF if it’s protected with a password (otherwise, the splitting task will be unsuccessful).

Taking everything into careful consideration, while hardly impressive in any tangible way, WonderfulShare PDF Split Pro is one of those perfect examples of lightweight apps that do their simple job fast and easy.

Even though the app works well, looks good and is novice-accessible, we should point out that a preview feature would have been quite useful, but this by no means a deal breaker.

What’s New

What’s New in this version:
– A new way of preview the splitting result in the file explorer window.
– The option ‘Convert to Text’ added in the right-click menu, it is a very powerful tool for text recovery.
– Bug fixed in file list.Q:

Show that $Z$ is a closed set

Let $\mathcal{H}$ be a normed vector space and $Z=\{z\in\mathcal{H}: \|z\|=1\}$.
Show that $Z$ is a closed set.
Attempt:
I’m trying to use the definition of closedness, but I don’t know how to proceed.
Any suggestions?

A:

As you correctly pointed out,
$$\overline{Z}=\{z\in\mathcal{H}: \text{there exists }z_n\in Z \text{ such that } z_n\to z\}$$
Notice that
$$\|z_n\|=1, z_n\to z\implies \|z_n-z\|=\|z_n\|\|z\|=\|z_n\|\to0\implies z_n\to z$$
This means that $z\in \overline{Z}$.
On the other hand, notice that if $z_n\in\overline{Z}$ (i.e. there exists a sequence $\{z_n\}$ such that $z_n\to z$), then $z\in Z$ and $\|z_n\|=1$, eea19f52d2
