If I have received $1000000us, first of all, I am glad that I have such good luck to get the money. There is no doubt that although it is a drop in the bucket for the rich, it is not worth mentioning, but I am very satisfied that I can have it. Because, this money may be a lot of people want to live a better life, hard life is also difficult to earn so much money, it is possible that many people also have lofty ideals, but they do not have enough money to realize their life value, maybe there are also many people are having, but did not cherish and regret. From this point of view, I am a very lucky person. But when I think that I only have one day to hold the money, I can't help feeling that there are some fly in the ointment.

Firstly,I have to congratulate myself being so lucky to receive this money; no doubt to a man of wealth,this money is just a drop in the bucket,but for me,I am very satisfied to have it.This is becaus...

I'm glad to hear from you. I think it's a good thing to say what you think. Except for the people who are talking behind their backs, too many people don't say what they think. However, sometimes being outspoken can do more harm than good. For example, a girl asks if she is fat, and your bat asks if his breath smells bad. In this case, you know the truth is not really good, But you'd better keep your ideas and think twice

How to turn angle into radian without calculator?
1200°

1200 ° times π / 180 degree
1°=π／180°
1 radian = 180 ° / π

2009 & # 179; + 2009 & # 178; - 2010 points 2009 & # 179; - 2 * 2009 & # 178; - 2007 simple operation help me
2009 & # 179; + 2009 & # 178; - 2010 points 2009 & # 179; - 2 * 2009 & # 178; - 2007 simple operation help me

2009³+2009²-2010=(2009²-1)(2009+1)
2009³-2*2009²-2007=(2009²-1)(2009-2)
2009-1
Answer: 2010 is better than 2007

Let the first n terms of sequence {an} and Sn = 4 / 3an - (1 / 3) * (2 ^ (n + 1)) + 2 / 3, n = 1,2,3 How to do the second question?
Let the first n terms of sequence {an} and Sn = 4 / 3an - (1 / 3) * (2 ^ (n + 1)) + 2 / 3, n = 1,2,3
(1) Finding the first term A1 and the general term an
(2) Let TN = (2 ^ n) / Sn, n = 1,2,3 It is proved that T1 + T2 + T3 + Tn< 3/2
Second question!?

a1=2
Sn=4/3an-(1/3)*(2^(n+1))+2/3,
Sn-1=4/3a（n-1）-(1/3)*(2^n)+2/3,
Subtraction
an=4/3an-4/3a（n-1）-(1/3)*(2^n)
an=4a(n-1)+2^n
4an-1=4^2*a(n-2)+4*2^(n-1)
...
4^(n-2)a2=4^(n-1)*a1+4^(n-2)*2^2
Superimposed above
an=4^(n-1)*a1+2^n+4*2^(n-1)+...+4^(n-2)*2^2
=2^(2n-1)+2^n*[2^（n-1）-1]
=2^(2n)-2^n
2) Let TN = (2 ^ n) / Sn
Sn=4/3[2^(2n)-2^n]-(1/3)*(2^(n+1))+2/3
=4/3*2^(2n)-2^(n+1)+2/3
Tn=(2^n)/Sn
=1/[4/3*2^n-2+2/(3*2^n)]
=3/2*【1/（2^(n+1)+1/2^n-3）】
Tn

In the triangle ABC, CoSb equals minus five thirteenth and COSC equals four fifths. Find the area of triangle ABC
The absolute value of BC is 2

According to the sine theorem: BC / Sina = AC / sinb2 /

Please design a dichotomy algorithm to find the root of the equation f (x) = x ^ 5 + X-1 in (0,1)

If there is no special requirement, first observe the function
f0＝－1,f1＝1
F derivative = 5x ^ 4 + 1 > 0, simple increase
It can be seen that there is only one solution on (0,1)
Then set a value like 0.001
Lower limit 0, upper limit 1
Calculate the function value of the midpoint 0.5 of the lower and upper limits
If it is greater than 0, set 0.5 as the new upper limit; if it is less than 0, set 0.5 as the new lower limit
Repeat the calculation until the difference between the upper and lower limits is less than 0.001
