I would like to share with you what happened to me!!

1.It is recommended to go to Mrs. Jin's beauty salon again, tell him that he has no credibility for a powerful relationship, and if the other party cannot solve it satisfactorily, he will implement 2 articles.

2.It is recommended that you go to the Cangzhou Consumers Association to complain 2080315, if there is a contract, and it is best within the validity period. Article 3 can no longer be implemented.

3.It is recommended to repost this post on all forums in the Cangzhou area to make Mrs. Jin famous.

The best thing to say about the great relationship of the article is to listen to with the beauty salon!

I'm in sales, and I suggest you learn from me and say out loud when you're upset: Great! This kind of thing happened to me, and it must have a cause and effect to happen, and it will be beneficial to me! A three-time course of treatment works!

Alas, people nowadays only recognize money, but they have to be reasonable to make money, they are inhumane like this, and they don't want to think about what to do if they touch this themselves, so these people are selfish enough, but after all, we have spent this money, and we don't have to come back, so we should buy a lesson and give ourselves an experience, and friends who have seen it should resolutely not go there.

Very sympathetic to you!

There are many beauty salons that take such a ** way to deceive people, and everyone should also be vigilant in other consumption!

There's no formal agreement, and there's nothing you can do.

Therefore, you must be careful in the future, and there must be written documents when it comes to interests.

Sympathize with you and never go to that beauty salon again to support you.

Black is really black! Isn't this a violation of consumers' right to know?

Complain about her. This thing must be complained.

complained about it, and turned against him.

Fight consumer complaints**.

You're a lot like me.

I was also the first boy in my class since I was in junior high school, until I lost my first monthly exam, and I was always second in my class.

The first time I didn't have a first, of course I was in a bad mood, but I'm not like you, and I think that's probably a good thing for me.

How to put it, people need to compete, and you can't progress without opponents. This time he surpasses me, I will work harder, thinking about how to surpass him - so that you surpass me, I surpass you, and a virtuous circle will be formed!

As for it laughing at you, that's his immaturity. The ancients said that "arrogant soldiers will be defeated", although my classmate won me, he was very low-key. So as for this aspect, I don't think it's a big problem, the best way is to ignore it, if it affects your normal learning, you can be like a teacher, educate it well; Moreover, it is foolish to say that he influences you is nothing more than that you are unable to study and review seriously, and you let his conspiracy succeed because you are not strong, and excluding the influence of surrounding factors is a necessary psychological quality for an excellent student.

In fact, you don't have to worry too much, the monthly exam and the midterm exam are just quizzes, the real battlefield for you to go to junior high school is the high school entrance examination, and you yourself say that you still have a long way to go - our teacher says in every class: "It doesn't matter if you lose once, just don't lose a second time; It doesn't matter if you lose the second time, just make progress! "This is a very reasonable sentence, every time you improve a little, every time you improve a little, you may become the champion by the time you get to the high school entrance examination, right?

You don't have to be too anxious, in fact, after you fail, I believe that one day you will surpass him and return to your original position or even higher! I'm working hard now, and you have to do it too!

Let me give you some advice.

1.Don't be discouraged after failure, listen carefully to the commentary, and be 100 points behind.

2.Lessons learned: Was it the wrong approach or was it too careless to even write down what should have been rushed.

3.I don't care about the so-called "introduction to the learning methods and experiences of top students", because their methods are often not the same as ordinary people like us, we should find our own methods, remember not to. Dead reading, pay attention to the combination of work and rest!

Again, let me correct your thinking that "my table mates are from the countryside" is not right, rural children are sometimes very powerful, maybe they are more willing to endure hardship!

Hope that helps.

I'm not a psychiatrist, I'm a peer, and communication without a generation gap is the most real!

It feels like you're paying too much attention to this exam, you're too nervous, and you need to learn to relax.

What pressure is there in the first year of junior high school, learn what you should learn, and watch what you shouldn't learn, but you must have confidence in yourself, if you don't accept other ridicule, you will press him in everything you usually do, and then teach him a lesson.

a+c=120°，c=120°-a

by the sine theorem.

a/sina=c/sinc

a=(3^(1/2)-1)c

sina=(3^(1/2)-1)sinc

3^(1/2)+1)sina=2sin(120°-a）=3^(1/2)cosa+sina

sina=cosa

a=45° or a=135° (rounded).

So a=45°

f(x)=cos2x+asinx

1-2sin^2x+asinx

2(sinx-a 4) 2+1+a 2 2x belongs to [30 degrees, 90 degrees].

1/2<=sinx<=1

When 1 2 < = a 4< = 1.

f(x) has a maximum value of 1+a2 2=3

a=201.

The maximum value of f(x) is a=3

a=3 (rounded).

So a=2,c=2 (3 (1 2)-1)=3 (1 2)+1s abc=acsinb 2=2*(3 (1 2)+1)*(3 (1 2)) 2 2=(3 (1 2)+1) 2

Please feel free to use it.

If you have any questions, please feel free to ask.

Neither will I! Pray to the Great God! Tell me about it, too.

1. The average value of the voltage Uo at both ends of the load resistor uo=;

2 The average value of the load current io io=uo rl=140 80=;

3 The average value of the current flowing through each diode id=;

4. The diode is subjected to the maximum inverting voltage UDRM= 2UI=220V;

5. If the positive and negative polarity of the diode D1 is reversed, the positive half cycle of the rectifier circuit cannot be turned on, and the negative half cycle will be short-circuited, resulting in the burning of D1, D2 and the transformer output coil.

6. If the diode D1 is broken down and shorted, the negative half cycle of the rectifier circuit will be short-circuited, burning D2 and the transformer output coil.

Why can't you send it?
