Yoni Smadja dx is the difference between two points . A difference which is almost equal to zero , but not zero . U might say this difference is equal to 1/100 or 1/1000 or 1/100000000 or 1/10000000000 , yes the amount of difference which I mentioned above is very very small and almost equal to zero , but they are still some values which you can see and count. dx is some thing that small that a human can't imagine . It's just a previous point before zero , which is obviously not understandable for humans.you can make any number as small as you can by putting more zeros in ur denominator as I did in above examples, but u can never achieve to a point which is just a previous point before zero.
So the conclusion of my comment is that dx which is a difference between two points
Let's say difference between points
X and a
so , dx = x - a
Such that x is almost equal to a
Which we say in mathematics as" x proceeds to a" . An arrow symbol is used to say this phrase which I don't have here.
Than you can say that
dx proceeds to zero
It's a very beautiful concept in mathematics derived by humans. As we are staying at a same point because x and a are almost equal but at the same time we find a difference at that point.
Hope.u get something..
PS: After you're done with Differential Calculus, It would be really great if you do the same approach of explaining the theory behind Linear/Multi-linear/Matricial and/or Tensor Algebra. Or maybe get into Stochastic Calculus as it's on the same lines of the current series. Applying your approach to these subjects would be really enlightening since they almost look daunting when you try to get to the bottom of the theory.
Although foreigners may now invest in A-shares, there is a monthly 20 percent limit on repatriation of funds to foreign countries.
Performance of A-shares.
Since its inception in 1990, including a major reform in 2002, the index has seen great fluctuations. Overall, however, it has grown along with the Chinese economy. The years 2015 to 2016 were a particularly difficult period, with a 52-week performance of -21.55 percent as of July 20, 2016.
As China grows from an emerging market to an advanced economy, there is substantial demand for Chinese equity. Stock exchange regulators continue efforts to make A-shares more broadly available to foreign investors and have them recognized by the global investing community.
In June 2017, the MSCI Emerging Markets Index announced a long-awaited decision it would add stocks to its index. According to CNBC, MSCI will add 222 China A Large Cap stocks to its benchmark emerging markets index gradually beginning in 2018. The MSCI website reveals the stocks it will list include the Bank of China, China Merchants Bank, Guotai Junan, Ping An Insurance, according to a document on Tsingtao Brewery, SAIC Motor, Suning Commerce and Spring Airlines.
Current Dividend Preference.
Participating Preferred Stock.
Convertible Preferred Stock.
Cumulative preferred stock includes a provision that requires the company to pay preferred shareholders all dividends, including those that were omitted in the past, before the common shareholders are able to receive their dividend payments.
Non-cumulative preferred stock does not issue any omitted or unpaid dividends. If the company chooses not to pay dividends in any given year, the shareholders of the non-cumulative preferred stock have no right or power to claim such forgone dividends at any time in the future.
Participating preferred stock provides its shareholders with the right to be paid dividends in an amount equal to the generally specified rate of preferred dividends, plus an additional dividend based on a predetermined condition. This additional dividend is typically designed to be paid out only if the amount of dividends received by common shareholders is greater than a predetermined per-share amount. If the company is liquidated, participating preferred shareholders may also have the right to be paid back the purchasing price of the stock as well as a pro-rata share of remaining proceeds received by common shareholders.
