Give students answers to all questions.

Explain in extreme detail how each result was reached.

Students have the amazing capacity of not looking at answers if they don't want to.

And when they've had enough, then can read answers and understand while the problem is fresh in their minds.

If you don't give answers, no one will be able to use your online material without you being there to hold their hands.

Forbidding students from publishing their answers also goes against let students learn by teaching.

Then, if people find errors, or have questions, they will write a comment near the content itself.

Then, next person that comes along and has the same problem, will also find that comment, and your answer will solve their problems too.

The perfect way to do this is to use GitHub issues

Just make it very clear what you've tried, what you observed, and what you don't understand if anything at all.

This will already open up room for others to come and expand on your attempt, and you are more likely to learn the answers to your questions as they do.

And there's a good chance someone who knows more than you will come along and correct or teach you something new about the subject. For example, this has happened countless times to Ciro Santilli when doing Ciro Santilli's Stack Overflow contributions.

Perfect is the enemy of good.

This section is about functions that operate on numbers such as the integers or real numbers.

First published by Fourier in 1807 to solve the heat equation.

Euphemisms are evil bullshit.

Just say what you mean to say,

Don't be a pussy.

If you've been fired, say you been fired, not "let go".

If someone died, say they died, not "passed away".

A more specific type of E-learning website generally run by a specific organization.

A website, usually hosted by an university, that takes what is done in class, and pastes it online. It is already much more rational and efficient, and opens up the way for potential sharing outside of the institution (or by default paywalling as the University of Oxford did.

The fundametnal problem with VLEs is that they tend to not have enough incentives for students to contribute at all to the content. This is basically the major motivation behind OurBigBook.com.

Given a function $f$:we want to find the points $x$ of the domain of $f$ where the value of $f$ is smaller (for minima, or larger for maxima) than all other points in some neighbourhood of $x$.

In the case of Functionals, this problem is treated under the theory of the calculus of variations.
