What does the upper and lower bounds mean? Thank you!!!

The upper limit is the highest, and the lower limit is the lowest. The upper and lower limits refer to the values in an interval from high to low.

The upper limit, which refers to the earliest time or the largest quantity limit, is the opposite of the "lower limit".

The lower limit refers to the minimum of something or something.

When the upper and lower limits of the integral are not a simple variable x, but a function of x, as in this problem, the derivative of the composite function is used. With the introduction of the intermediate variable u=sinx, the function is seen as a function of the upper limit of the integral (0 to u) sin(t 2)dt (denoted as f(u)) and the function u=sinx. So the derivative of the function for x = f'(u)×u', here f'(u) is a simple derivative of the integral upper limit function.

According to the modern Chinese dictionary, the interpretation of these two words is: upper limit: the earliest or largest limit of time (as opposed to the "lower limit"); Lower Limit:

The latest or smallest limit (as opposed to the "upper limit"). As for the comparison, you should be able to read it yourself.

The meaning of the upper limit is actually relatively simple, generally speaking, we will say that the upper limit of a hero is very high, which means that if this hero plays well and plays to the extreme, then it is a hero who is almost incomprehensible, and it is difficult to find a way to limit him. The lower limit is the minimum that can be achieved.

If you can't play, then Li Bai's role is very low, you won't brush the ultimate, then you will lose the most important output, and you won't use skills to block skills.

Then it's hard to come back after entering the game, so Li Bai plays poorly, it's really a hero who can be sent all the time, and has no damage and no effect, but on the contrary, those heroes with lower difficulty, such as Hou Yi, even if you don't know how to play, as long as you know how to carry out ordinary attacks, once you reach the middle and late stages, and there are teammates by your side, then you can still play good damage, which is the lower limit high.

Generally describe some heroes with relatively high difficulty, and there are many displacement skills, and even the skills of the opponent can be resisted, take Li Bai as an example, if you play well, you can easily cut the back row and hit high damage and return to the original point, there is no way to take him, even if you use skills, he can also dodge.

Li Bai's ceiling is relatively high, as long as he plays very well, can use skills to dodge skills, and play damage in the process, in most heroes, few people can limit him, this is the upper limit of a hero, when these heroes are in the hands of the high play god, it is difficult to block, and how to judge whether the upper limit of a hero is high enough.

Basically, just look at the common heroes of the gods.,The heroes used by high-level players have a high ceiling.,The reason is that each other is a god.,The upper limit of heroes is more important.。

The upper limit is the highest, and the lower limit is the lowest. The upper and lower limits refer to the values in an interval from high to low.

How to distinguish between upper and lower bounds:

1. The meaning is different. The upper limit is the maximum capacity output; The lower limit is the bottom line that can be tolerated.

2. The meaning is different. The upper limit refers to the earliest time or the maximum quantity limit; The lower limit refers to the minimum of something or something.

The upper limit and the lower limit can be said to be opposites, the upper limit is the largest party, the lower limit is the smallest party, in the process of application, the two can be in a state of contrast, but the value is completely different.

The upper and lower bounds are used a lot in mathematics, for example, when the upper and lower bounds of the integral are not a simple variable x, but a function of x, the composite function is used at this time.

The law of derivation.

Referring to the intermediate variable u=sinx, the function is seen as a function with an integral upper bound.

0 to u) sin(t 2)dt and the function u=sinx symbol.

So the derivative of the function to x f(u) u, where f(u) is a simple derivative of the integral upper limit function.

Of course, the application of the upper and lower limits is not only that, but in the process of choosing an application, it is necessary to understand the difference between the two and then carry out detailed planning.

The upper limit is the highest, and the lower limit is the lowest. The upper and lower limits refer to the values in an interval from high to low. The upper limit, which refers to the earliest time or the largest quantity limit, is the opposite of the "lower limit". The lower limit refers to the minimum of something or something.

The upper limit comes from Zeng Fan's "Song Tomb of Daping Forest Farm in Shunchang, Fujian": "The Kamakura period in Japan is about equivalent to the Southern Song Dynasty in China, so the upper limit of the Tong'an kiln age is pushed to the Southern Song Dynasty. ”

The lower limit comes from Huang Liuhong's "Fuhui Quanshu, Qiangu, and Bi Limit Theory": "Therefore, the limit should not be too urgent, nor too slow. ”

1. The upper limit is the highest, and the lower bridge is the lowest. The upper and lower limits refer to the values in an interval from high to low.

2. The limit refers to the earliest time or the largest quantity limit, as opposed to the "lower limit of sensitization".

3. The lower limit refers to the minimum of something or something.

4. When the upper and lower limits of the integral are not a simple variable x, but a function of x, as in this problem, a composite function is used.

The law of derivation. With the introduction of the intermediate variable u=sinx, the function is seen as a function with an integral upper limit.

0 to u) sin(t 2)dt (denoted as f(u)) is formed by the function u=sinx. So the derivative of the function to x = f(u) u, where f(u) is a simple derivative of the upper limit of the product of repentance.

What does the upper and lower limits mean1.The upper limit of hail is the highest source and the lower limit is the lowest. The upper and lower bounds refer to a range of values from high to low.

2.The limit is the earliest hail period or the maximum number of limits, as opposed to the "lower limit".

3.The lower limit refers to the minimum of something.

4.When the upper and lower bounds of the integral are not simple variables x, but a function of x, as in this problem, the derivative rule of the composite function is used. The intermediate variable u=sinx is introduced, and the function is considered to consist of an integral upper limit function, which is equal to the function u=sinx, and is divided into three parts: .

The derivative of the function for x = f (u) u where f (u) is the derivative of the integral upper bound function.

The upper limit, which refers to the earliest time or the largest quantity limit, is the opposite of the "lower limit". The lower limit refers to the minimum of something or something. The "upper limit" is the highest, and the "lower limit" is the lowest. The upper and lower limits refer to the values in an interval from high to low.

When the upper and lower limits of the integral are not a simple variable x, but the number of closed letters of x, as in this problem, the derivative of the composite function is used. With the introduction of the intermediate variable u=sinx, the function is seen as a function of the upper limit of the integral (0 to u) sin(t 2)dt (denoted as f(u)) and the function u=sinx. So the derivative of the function for x = f'(u)×u', the f in this shroud'(u) is a simple derivative of the integral upper limit function.
