Reading answers of mahogany
In front of my hometown in the countryside, there is a large space for people to plant mahogany seedlings
Mahogany is a special kind of tree. It is graceful, tall and straight. Many mahogany trees were planted in the old forest farm. The mahogany trees in the forest farm are as tall as several feet. So when I see the seedlings of mahogany that only reach knee, I can't believe my eyes
A tall man planted mahogany seedlings. When he bent down to plant trees, he felt like transplanting seedlings. The difference is that this is a dry land, not a paddy field
After the seedlings were planted, he always watered them every few days. Strangely enough, the number of days he came was irregular, sometimes three days, sometimes five days, sometimes more than ten days. The amount of watering was not certain, sometimes more, sometimes less
When I lived in the countryside, I would take a walk on the path beside mahogany seedlings every day. The planter would come to my house occasionally for tea. Sometimes he would come in the morning, sometimes in the afternoon, and the time was not certain
I feel more and more strange
What's more strange is that mahogany seedlings sometimes wither inexplicably. So, when he comes, he always brings some seedlings to replant
At first I thought he was too lazy to water the tree after so long
But how do lazy people know how many will wither?
Later I thought he was too busy to do anything according to the rules. But how can a busy man do things so calmly?
I can't help asking him, when should I come? How often should I water it? Why does mahogany wither for no reason? If you water it every day, wouldn't mahogany wither so easily?
The man who planted trees laughed and said, "planting trees is not growing vegetables or rice. Planting trees is the foundation of a hundred years, unlike vegetables, which can be harvested in a few weeks. Therefore, trees should learn to find water sources in the soil. I just imitate the weather when it rains. It's not accurate. How many days does it rain? In the morning or afternoon? How much does it rain at a time? If it can't grow in such uncertainty, how much does it rain, The saplings will naturally wither. But as long as the saplings can find water in the uncertainty and try their best to take root, it will not be a problem for them to grow into a hundred year old tree. "
"If I come to water every day and water a certain amount regularly every day, the saplings will develop a heart of dependence, and their roots will float on the ground and can't go deep into the ground. Once I stop watering, the saplings will wither more. Fortunately, the surviving saplings will collapse when they encounter a storm."
The words of the tree growers make me ponder deeply. If you input this, isn't it true for the tree growers? People who live in turbulence can stand the test of life. Because in turbulence, we will develop an independent heart. In turbulence, we can easily learn the ability to survive
The law of life can not be so fixed, so perfect, because the fixed and perfect law, will form your passive state, and this state is very likely to let you gradually wither
When they walk into the mahogany seedlings again, something will always be touched in their heart. These seedlings are trying to face the uncertain wind and rain, trying to learn how to find sufficient water and how to breathe in the sunshine. Once they learn these skills, their century old foundation will be laid
Now, the mahogany seedling in front of the window has grown as high as the roof, so elegant and comfortable
The tree growers are no longer here, and the mahogany will not wither

(1) Q: why does mahogany wither for no reason?
A: unable to grow in this uncertainty, the saplings will wither naturally
(2) Q: if you water it every day, mahogany won't wither so easily, will it?
A: if I water it every day and pour a certain amount every day, the saplings will develop a heart of dependence. The roots will float on the ground and can't go deep into the ground. Once I stop watering, the saplings will wither more. Fortunately, the surviving saplings will collapse when they encounter a storm. "
4. What do you think of after reading this article?
A: I think it's the same with planting trees, isn't it the same with cultivating people? People who live in turbulence can stand the test of life. Because in turbulence, we will develop an independent heart and won't rely on it. In turbulence, we are easy to learn the ability to survive. People will certainly encounter all kinds of difficulties in society, and they need to face them by themselves, A person will really mature

Let f (x) be a function defined on real number set R, and for any real number x, y satisfy f (X-Y) = f (x) + F (y) + XY-1 construence
Find the analytic expression of function f (x).


y=0
f(x)=f(x)+f(0)-1,f(0)=1
y=x
f(0)=f(x)+f(x)+x²-1
2f(x)=-x²+2

Is there a left / right derivative in the derivative


Although I haven't heard of this kind of expression, such a function is certainly possible. It is obviously possible to define g (x) as f '(x -)
It's easy to define, but if it's not very useful, there's no need to define it

In time image, if the image is a curve, then the instantaneous acceleration at a certain time is equal to the slope of the tangent passing through the image at that time
Then why should the slope of tangent be calculated by the scale of coordinate system instead of the tangent of tangent angle


Because the scale is taken artificially, you can count 1cm as a unit, or 2cm Therefore, the scale of abscissa and ordinate may be different. When the scale is not unified, the curve drawn by the same group of data may be different (there is a same situation, that is, when the abscissa and ordinate are expanded or reduced by the same multiple at the same time under the unified scale), and the slope may change. Therefore, it is better to use the data to calculate the slope rather than the triangle
