Algorithms on Web Pages with Left Copy Licenses

For example, you find algorithms on websites like wikipedia or codeproject. For example, https://en.wikipedia.org/wiki/Damerau%E2%80%93Levenshtein_distance or https://www.codeproject.com/Articles/11157/An-improvement-on-capturing-similarity-between-str .
These pages are under creative joint licenses. You are therefore not authorized to use them in works which are not under such a license.
I also read that the algorithms are not under such licenses.
So when you follow the description of such a license and create code based on the descriptions of these CC-SA protected web pages, is it legal?

orthogonality – Show that a finite set $ B = left {1, x, x ^ 2 right } $ is an orthonormal system with respect to the interior product

Here's my problem:

Show that a finite set $ B = left {1, x, x ^ 2 right } $ is a system orthonormal to the inner product $ left langle f, g right rangle = int _ {- 1} ^ 1 : f left (t right) cdot g left (t right) dt $ for all $ f, g in L ^ 2 left (-1, 1 right) $.

And then there is a clue: assess $ left langle 1, x right rangle, left langle 1, x ^ 2 right rangle and left langle x, x ^ 2 right rangle $. As far as I'm concerned, these are the indicators of orthogonality (if they are all zero then the whole is orthogonal). My results are consecutive $ 2x $, $ 2x ^ 2 $, and $ 2x ^ 3 $.

I don't understand – they are only worth zero if $ x = $ 0. Does this mean that the whole is not orthogonal – and therefore cannot be orthonormal? How to proceed with this problem?

css – How could I rewrite this simple table without using a table? Have 2 divisions side by side and the one on the left being centered

I am trying to improve my skills. It's extremely simple to do what I want with a table like this

Thing_____ Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

However, I thought it would be easy to do without a table and I did not go near the broken text. It looks like a car accident. I was wondering if there was a simple way to do it without a table? or should i use a table even if it isn’t really a table?

How to make a curved angle between the left menu bar and the top menu bar?

I am trying to make the curve that you can see in this image between the left menu bar and the top bar. I want to do it in Adobe XD or Illustrator, but I don't know how.

optimization – Solve the minimax problem $ min_ {x in mathbb {R} setminus {0 }} max_ {t in[alpha,beta]} left | prod_ {i = 1} ^ {n} (1-xt) right | $

Let $ 0 < alpha le beta $. I want to solve the minimax problem
$$ min_ {x in mathbb {R} setminus {0 }} max_ {t in ( alpha, beta)} left | prod_ {i = 1} ^ {n} (1-xt) right | $$

Please note that I have no experience in optimization.

My attempt:

Since $$ left | prod_ {i = 1} ^ {n} (1-xt) right | = prod_ {i = 1} ^ {n} | (1-xt) | = | 1-xt | ^ n $$
and transformation $ x mapsto x ^ n $ on the real positive does not change the minimum I can consider
$$ min_ {x in mathbb {R} setminus {0 }} max_ {t in ( alpha, beta)} left | (1-xt) right | $$

Now, intuitively, I would say that $ x _ * = frac {1} {avg ( alpha, beta)} = frac {2} { alpha + beta} $ is the solution.

Is this correct and how could we solve this problem using optimization theory and how could I prove it without using theory?

unit – move the enemy to the left in the movement of the wave of sin over time

I am trying to create a descending shooter where the enemy moves in a sinusoidal movement over time. During the first 10 seconds, the enemy must move only to the left and after that, he must move to the left in the movement of the waves of sin. Here is the code I am using. "

public float enemySpeed;
float frequency = 5.0f;
float magnitude = 1.8f;

void FixedUpdate()
{
    if(Time.time < 10.0f)
    {
        transform.Translate((enemySpeed* Vector2.left) * Time.deltaTime);
    }
    if(Time.time >= 10.0f)
    {
        transform.Translate(enemySpeed* -1.0f * Time.deltaTime, 1.0f * Mathf.Sin(Time.time * frequency) * magnitude * Time.deltaTime, 0);
    }`

What happens is that during the first 10 seconds the enemy simply moves to the left, but after that all the enemies on the screen start to move in movement of the waves of sin. What I want to achieve is that if the enemy has already appeared before the 10th second, he should move to the left with no movement of sin. Right now, if the enemy is in the middle of the screen and the time is more than 10 seconds, even that enemy begins to move in the movement of sin.

The upper area affects my right and left area

I use sharepoint 2013 sites as part of a work tool.
I can't explain anything to you as it is covered with confidential documents, but I will try to illustrate my problems.

So every site I get comes with this default zone construction
width of an upper, left and right area that looks like a part 66/34

Default configuration

The problem is
As soon as I add a Web Part to the upper area, it changes the relationship between the left and right areas
After adding a Web Part to the upper area

I do not want that :]
but as far as i can't say anything, i add a fixed width or height.
So why does adding something to the top bar change by default?

Right and left costs

I am really struggling with this problem:

Determine the left and right cosets in $ mathbb {Z_6} $ of the subgroup $ langle3 rangle $ generated by $ overline3 $.
