Fundamental theorem of calculus

Here's an example of the chain rule. Suppose we want to calculate:
$$
\dv{e^2x}{x}
$$
So we have:
$$
f(x) = e^x \\
g(x) = 2x
$$
and so:
$$
f'(x) = e^x \\
g'(x) = 2
$$
Therefore the final result is:
$$
f'(g(x))g'(x) = e^{2x} 2 = 2 e ^{2x}
$$

A scribe is a person who serves a professional copyist. The work of scribes can involve copying manuscripts and other texts as well as secretarial and administrative duties such as the taking of dictation and keeping of business, judicial and historical records for kings, nobles, temples and cities. The profession has developed into public servants, journalists, accountants, bookkeepers, typists, and lawyers.

One of the most important professionals in ancient Egypt was a person educated in the arts of writing and arithmetic. Scribes were considered part of the royal court, were not conscripted into the army, did not have to pay taxes and were exempt from the heavy manual labor required of the lower classes.  Sons of scribes were brought up in the same scribal tradition, sent to school and inherited their fathers' positions upon entering the civil service. Much of what is known about ancient Egypt is due to the activities of its scribes and the officials. Monumental buildings were erected under their supervision, administrative and economic activities were documented by them, and stories from Egypt's lower classes and foreign lands survive due to scribes putting them in writing.

In addition to accountancy and governmental politicking, the scribal professions branched out into literature. The first storeis were probably religious text. Other genres evolved, such as wisdom literature, which were collections of the philosophical sayings from wise men. These contain the earliest recordings of societal thought and exploration of ideas in some length and detail.

In the Middle Ages, every book was made by hand. Specially trained scribes had to carefully cut sheets of parchment, make the ink, write the script, bind the pages and create a cover to protect the script. This was all accomplished in a writing room called a scriptorium which was kept very quiet so scribes could maintain concentration. A large scriptorium may have up to 40 scribes working. Scribes woke to morning bells before dawn and worked until the evening bells, with a lunch break in between. They worked every day except for the Sabbath. Scribes were only able to work in daylight, due to the expense of candles. 

The scribe was a common job in medieval European towns during the 10th and 11th centuries. Many were employed at scriptoria owned by local schoolmasters or lords. These scribes worked under deadlines to complete commissioned works such as historic chronicles or poetry. 

These scribes would meticulously record the information presented in the texts, but not mindlessly. In the case of herbals, for instance, there is evidence that the monks improved upon some texts, retracted textual errors, and made the text particularly relevant to the area in which they lived. Some scribes even went so far as to grow some of the plants included in the texts. They had little room or patience to disseminate the imaginary plants. The writers truly restricted themselves to only include practical information.

Meanwhile, in the case of bestiaries, the scribes generally copied and cited previous texts to pass them on. Unlike the herbals, the scribes could not grow an animal in their garden, so largely the information taken from the bestiaries was taken at face value. 


In the 13th century, Paris was the first city to have a large commercial trade of manuscripts, with book producers being commissioned to make specific books for specific people. Paris had a large enough population of wealthy literate persons to support the livelihood of people producing manuscripts. 



Wait, why the paragraph break doesnt work at all?

I can not join your movement because I really have more reasons than other ones. For privacy, I can't explain that. And, For me, I know that for the current situations in China, I can't do anything. For China, I think only solution is revolution not reform. The protesters will die with nobody know that without tech. People could try, but it is a Way of Sacrifice.

According the report, this organization help programthink arrested. I research that for some days, and the evidences express its correctness.


净网志愿者协会, may one day you will be captured by them. But you are foreigner, they don't have a way to do that.


净网志愿者协会, it is a semi-official organization but with high-tech hacker technology. You know, in China, high-tech hackers will not be an offical. Because it is a semi-official organization with many young  little-pink engineer, the tracking for programthink, it could be done.


They are actually not wumao, but they may be more formidable opponent. But you live aboard, they can't do anything and officals will not always listen their views.


Why do I think its claim for programthink's arrest is credible? Because some inference.
The organization says programthink is 马勇康.
https://github.com/programthink/zhao/issues/418


one year passed, 2022/05, offical media(only media) say 马某某，煽动分裂国家、煽动颠覆国家政权
https://baijiahao.baidu.com/s?id=1731886110528251526&wfr=spider&for=pc


the 马 first name only has 1% population in China. Coincidence? And according the report's keyword: 浙江温州, 科技有限公司，“洗脑”，“人生导师”，顽固


just like a copycat keyword for programthink blog and it conforms characteristics.


and the organization say 马勇康 is 山东人, the offical media say he is 浙江人


According the data in the website or anywhere:
https://www.23mofang.com/ancestry/library-surname/5f34ee9eff5a3344d6a8aabe


浙江(ZheJiang province) have less 马 than 山东.
And programthink family's post say programthink lastly has a business travel to a city in eastern China, you see 温州，浙江，上海，all keyword is about the eastern China. 温州 is a interesting keyword, if you search programthink's issues, it has a strange 温州 people, but no other Zhejiang province's county.


And other crime such as 政治纲领, as I know for CCP cop, they need some more outstanding achievement. 继续调查中，because the CCP cop needs more news by the mouth even it is not neutral. And, it is possible that programthink think he could take the all blames on his shoulder maybe. 


These inference may is only inference by brain ———— we never know what is a truth.


https://www.bilibili.com/video/BV14S4y1T7RT/?spm_id_from=333.999.0.0
净网志愿者协会 mentions programthink in the video.


I only know that they may be the not many real high-tech little-pink and hackers and really can do that. They are more terrible cop, even sometimes, gov will not listen them. I don't know in 2022 the organizations like it will do what.


Sometimes I think what is better? For my reasons I know I couldn't join yours. And I can't keep "doublethink"(ps: I'm not an official, official never doublethink). The only difference between China and 1984 may is the war is peace. China gov officials say China love peace, and in fact, CCP indeed take less war than other countries. But it is Chinese nature, may CCP also keep something.


CCP is not worse like Russia, so it is more difficult, for any reform. And reform may not work too fast or really work, only revolution.
