Who can help me solve my doubts, who can answer my doubts?

Now that you have a certain dependence on smoking, your body has accepted the environment of long-term smoking, if you suddenly stop smoking or suddenly quit smoking, you will feel unwell and may get sick, so whether you smoke or quit smoking, it will take time to get used to it. Also, if you don't smoke for 8 hours, it is normal for you to feel dizzy and nauseous when you smoke suddenly, because I also smoke, and I feel the same way, I only smoke half a pack a day and already have such discomfort. It is recommended that you eat more fruits.

I also heard from a friend that if you want to quit smoking, chewing gum is also a good way to chew when you are addicted to smoking!

In addition to the nicotine and tar that people say, there is carbon monoxide, which can inhibit the oxygen-carrying capacity of red blood cells, reduce the oxygen content in the blood, and directly make the brain lack oxygen, causing people to feel dizzy and other adverse symptoms.

You want to smoke, mainly because your body needs nicotine. and lifestyle habits (want to hold a cigarette in your hand), dizziness after smoking is a hypoxic reaction.

Novice smokers (when learning to smoke) may have a more severe hypoxia, the symptoms are dizziness, lightheadedness, and yellowing, at this time, breathe fresh air, and rest for a while, it will be relieved by itself.

With the increase of smoking age, the self-resistance to carbon monoxide and adaptability increase. So the amount of smoke increases.

Smoking is harmless, don't make excuses, quit smoking!

A should be partially legally responsible, and robber B is primarily responsible, I guess, after all, I don't know much about the law.

For example, a doctor encountered an elderly man on the street who suddenly fell unconscious, and the situation was very critical. The doctor immediately performed resuscitation compressions while summoning passers-by for first aid**. The old man was successfully rescued, but because the doctor pressed too hard, one of his ribs was broken.

Does the doctor have to be held responsible for this broken rib?

A was willing to risk his life to provoke the robbers in order to save the lives of all the passengers on the plane. Robber B ** Passenger C, it was Robber B who intentionally killed people, and Robber B must bear legal responsibility, not by A who acted bravely.

I feel that the robbers should be held fully responsible.

A pays a small part of the responsibility, and the main responsibility lies with the robbers.

98 1 counts as a duplicate.

You borrowed a total of 100. I used 97 to buy shoes, and I had 3 yuan left, and I paid 1 yuan to my parents, that is, I still owed 98, and I bought 97 shoes, plus 1 yuan I kept, which was just equal to 98

97 yuan plus one dollar for yourself is not equal to 98 yuan owed to your parents. In fact, it is equivalent to borrowing 98 yuan from my parents.

1.The overall reason is that you have a problem with your integrity, and you promised and returned.

2.You dialed ** in advance, are you sure that the number is commonly used in their recruitment department**? If yes, how many times did you call and why they didn't pick it up.

3.There is a reason why their manager is very angry, you ** explained to him that you didn't, and gave them ** several times but didn't pick up. Or whether you should go and explain it in person on the day. If you sincerely apologize for this call and explain that you have contacted them, it is all clearly explained, it can be regarded as a salvation.

3.You're already planning to go, you're still struggling with something, it's a big deal to send an email or text message to express your apology, and then the matter is over, even if you can't get over it in your heart, there is nothing you can do, because the matter has passed.

At this point, you can apologize to the other person.

It's your own reason, explain it clearly to others, and apologize! If the other party forgives, they will generally forgive, and that's it! If the other party doesn't forgive, then let him go!

There is no need to keep it on your mind all the time! To tell the truth, the world is so big, where can't you go! As the old saying goes, **loess does not bury people, this is what it says!

So be yourself, there's no need to dwell on it!

(1+sina/√1+cosa - 1-cosa ) 1-sina/√1+cosa + 1-cosa)

(1+sina)(√1+cosa + 1-cosa)+(1-sina)(√1+cosa - 1-cosa)]/[(√1+cosa- √1-cosa)(√1+cosa + 1-cosa)]

2(√1+cosa )+2sina(√1-cosa)]/[(1+cosa)-(1-cosa)]

Because of the pie "a" 3 faction 2

So Pai 2 "a 2 "3 Pai 4

cos(a/2)《0 sin(a/2)》0

2 2[-cos(a 2)+sina*sin(a 2)] 2cosa half-width formula Remove the root number.

2√2[-cos(a/2)+2sin(a/2)*sin(a/2)cos(a/2)]/2cosa

-√2cos(a/2)[1-2sin(a/2)*sin(a/2)]/cosa

-√2cos(a/2)cosa/cosa

--2cos(a/2)

There should be no problem with simplification, but the plus and minus signs are not very bottomed, for your reference.
