Something troubles me for the time being. Too much homework makes me feel very stressed and I have to study all the time as well. I tried to talk to my parents to seek for comfort and told them that all work and no play makes Jack a dull boy, but it turns out that they cannot understand me at all. I feel really sad as well as helpless at present. I am even thinking of leaving home! What can i do now? I hope you will give me some advice. Looking forward to receiving your letter.
I haven't written this kind of article for a long time. I don't know whether it is up to standard or not. Please refer to it

Suppose your name is Jeff, a middle school student from the United States. After living in China with your parents for one year, you have an interesting discovery. For this reason, you write an email to your good American friend, jeeny, and share it with her
Writing points,
1. Every day in the street, we meet Chinese people who say "hello" to you. Different people say "hello" with different meanings
For example: character taxi driver meaning welcome you!
Does street vendor mean shopping?
Can you practice English with me?
In order to welcome foreign friends to Beijing Olympic Games, Chinese are studying English hard
3. I hope Jenny and her friends will come to watch the Olympic Games and feel the friendship of Chinese people from "hello"

Dear Students,
The English summer Camp will

Chapter 1: dear Jenny, I happy to find a very interesting fact with the word 'hello' in China. Usually, people having different meanings when they say 'hello'. For example, if a taxi driver says' hello

The drawing method of function image of y = 1
Please teach me the steps

Make a vertical line of y-axis through point (0,1)
This vertical line is the function image of y = 1

The difference between vector translation and function translation/

Vector translation only changes the position of the starting point and the ending point. The representation of vector remains unchanged, such as a = (1,2). As long as the coordinate system remains unchanged, the coordinate of a is always (1,2)
The function translation is different. Assuming that the coordinate system remains unchanged (of course, the coordinate axis moves, the function curve does not move, and the function curve moves, the coordinate axis does not move are essentially the same, just relative motion). If the translation vector is known to be B, we might as well take B = (B1, B2) (only two-dimensional space is considered), then the point on the translated curve might as well take P (P1, B2), P2) and Q (Q1, Q2) on the curve before moving must satisfy the following relation:
OP = OQ + B, that is, P1 = Q1 + B1; P2 = Q2 + B2;
Geometrically, all the points on the original curve move to the position of another point according to the direction and motion distance specified by the translation vector, but they are still in the same coordinate system, so the function expression has changed. The bridge connecting the two is the translation vector

As shown in the figure, bisectors BP and CP of the two outer angles of angle ABC intersect point P to prove that angle P = 90 ° - 1 / 2 angle A

Because ∠ a + ACB = 2 ∠ CBP (1)
∠A+∠ABC=2∠BCP (2)
(1) + (2), 2 ∠ a + ∠ ACB + ∠ ABC = 2 (∠ CBP + ∠ BCP)
And because ∠ ACB + ∠ ABC = 180 ° - A
∠CBP+∠BCP=180°-∠P
Therefore, 2 ∠ a + 180 °～ a = 2 (180 °～ P)
It can be concluded that ∠ P = 90 ° - 1 / 2 ∠ a

How to simplify complex formulas with unknowns by Maple?

Example: simplify (sin (x) + cos (x)) ^ 2
with(MTM):
simple((sin(x)+cos(x))^2)
In addition, combine, convert is very useful
Sometimes the simplest expression can only be obtained after the variable is assumed
Software is dead, people are alive

Given vector a = (x-1, y), vector b = (x + 1, y), and absolute value a-absolute value b = 2, then the trajectory equation of the moving point m (x, y) is

Analysis: given vector a = (x-1, y), vector b = (x + 1, y), then: module | vector a | = √ [(x-1) & # 178; + Y & # 178;], | vector B | = √ [(x + 1) & # 178; + Y & # 178;] and absolute value a-absolute value b = 2, then: √ [(x-1) & # 178; + Y & # 178;] - √ [(x + 1) & # 178; + Y & # 178;] = 2

As shown in the figure, in △ ABC, point E is the heart, extending the circumscribed circle of AE intersecting △ ABC at point D, connecting BD, CD and CE, and ∠ BDA = 60 ° (1) prove that △ BDE is an equilateral triangle. (2) if ∠ BDC = 120 °, guess what kind of quadrilateral bdce is, and prove your conjecture

(1) It is proved that ∵ BCA and ∵ BDA are both the circular angles of arc AB, and ∵ BCA = ∵ BDA = 60 °, and ∵ bed = ∵ bad + ∵ Abe, ∵ AE and be are the angular bisectors of ∵ BAC and
