Poems describing teachers as students


The spring silkworm is here, the silk is done, the wax torch is ashes, and the tears begin to dry. Anyway, it's dedication. It's about the same. You can see for yourself



Some beautiful sentences describing the teacher's concern for the students
I want to write a composition, the teacher is concerned about the students, want to use some beautiful sentences to do the beginning or end, the more the better, pay attention to the teacher is concerned about the students! Within 30 minutes!


1. Caring for students is the basic requirement of teachers' professional ethics. As a teacher, if he often punishes his students and abandons them, he must have a morbid psychology. On the contrary, a teacher will care for students, understand and respect learning
If you are a student, you will make him (her) open-minded, happy and positive. Because students will respect you more, listen to you more, cherish your labor and make you happy. Caring for students will make you pay more and gain more
2. Today, it rained. I didn't take my umbrella with me. The teacher came to me and said, "I'll take you home." when I got home, the teacher's clothes were half wet
3. Teacher's love I dare not despise, because she is great, the teacher is like a female eagle, and as students, we are like a newborn eagle
4. On the platform, by the desk, I shed a little bit of hard work, moisten the flower buds, nurture the peaches and plums, spring and autumn, boxing and sincerity
5. In my heart, I always feel that the ninth grade students are big children. They know everything and don't need the teacher's advice. However, in contact with the students, I suddenly find that although they grow up, they are still children and young. They also need the teacher's care and care. Teachers should not be stingy with their own language. Sometimes the teacher unconsciously utters a caring word, They will be closer to each other, inadvertently a kind reminder, they have unspeakable gratitude
6. I believe that most of our teachers love students from the heart. The key is how we can pass our love to the students and play a greater role in motivating them. This is a problem worthy of our consideration. To sum up my experience, caring for students can start from one sentence
7. The most sensitive thing in the world is the child's heart. Once the child's heart is hurt, the wound is not easy to heal. If every teacher has enough tolerance and patience, knows and learns to listen to the child's heart and let the child finish speaking, the effect may be completely different
8. Although some are small things, it is these seemingly ordinary details that affect the students' mind. Let's remember: one branch, one leaf, one world!
9. Think about the normal education and teaching. In the face of children's mischief and violation of discipline, some of our teachers either ridicule, sarcasm and scold, or preach aggressively. After a period of preaching, some children can't hold their heads up in front of the public, and they have the psychology of abandoning themselves and breaking the pot, Some even go to the opposite of teachers. How many teachers treat problems from the perspective of students, and how many teachers patiently listen to children's words?



2 / 1 х 3 / 2 х 4 / 3 х 5 / 4 х 6... 10 / 9 х 11 / 10 х 12... Please write the 100th formula according to the law


101/100*102



Mathematical rules: 3,4,5; 6,7,8; 10,11,12
Look at the following numbers to find the law:
3,4,5;6,7,8;10,11,12……
1. Calculate the sum of each group. What can you find?
2. Write your findings in letters


1. Calculate the sum of each group. What can you find?
3+4+5=4*3
6+7+8=7*3
10+11+12=11*3
2. Write your findings in letters
N + (n + 1) + (n + 2) = (n + 1) * 3 or
(n-1)+n+(n+1)=n*3



Please solve these mathematical equations: (to write process) 0 divided by (- 0.12) =? (- 0.5) divided by (- 1 / 4) =? (- 1.25) divided by 1 / 4=


0 divided by (- 0.12) = 0
(- 0.5) divided by (- 1 / 4) = (- 0.5) divided by (- 0.25) = 2
(- 1.25) divided by 1 / 4 = (- 1.25) divided by 0.25 = - 5



Mathematics God answers for me
For example, 2x + y + 3Z = 11, ① 3x + 2y-2z, ② 4x-3y-2z = 4, ③ the solution ① multiplies 2 - ② to get x + 8Z = 11 equation 4, ① multiplies 3 + ③ to get 10x + Z = 37 equation 5. Why can equation 1 be used twice?


Because the XY coefficient of 1 is small, multiplication is more convenient than division



1/4+1/5+1/6+.+1/(n+3) < 1/2


Do not understand the title, the first three numbers add up to burst



Given that x is greater than 2, find the minimum value of X + {4 / (X-2)}. His answer is that because x is greater than 2, X-2 is greater than 0, x + {4 / (X-2)} = X-2 + {4 / (X-2)} + 2 is greater than or equal to 2 √ (X-2) + {4 / (X-2)} + 2 = 6 -------- in this step, I don't quite understand why there is an additional 2 on the right after the solution of inequality is not equal to the original formula x + {4 / (X-2)}


First add 2 and then subtract 2, that is to make up for the denominator (x - 2) can be reduced, and then x + y is greater than or equal to the double root XY



I know the answer is y = X-1, the largest area is 8 times the root 2
The vertex of the parabola y ^ 2 = 4x is O, the coordinate of a is (5,0), the line L with an inclination angle of 45 degrees intersects the line OA (without passing through the point O or a) and intersects the parabola at two points m and n. The equation of the line L and the maximum area of the triangle MNA are obtained


Let the coordinates of the intersection of the line y = x + B and X axis be B (- B, 0), ||ab | = |5 + B | m (x1, Y1) n (X2, Y2)
The maximum area of triangle MNA is s = 1 / 2 * | ab | * | y1-y2|
If y = x + B and Y ^ 2 = 4x, then y ^ 2-4y + 4B = 0 | y1-y2 | = radical [(Y1 + Y2) ^ 2-4y1y2]
=Radical [16-16b] = 4 radical [1-B]
S = 1 / 2 * | ab | * | y1-y2 | = 2 | 5 + B | * radical [1-B] = 2 * radical [- B ^ 3-9b ^ 2-15b + 25]
[- B ^ 3-9b ^ 2-15b + 25] '= - 3B ^ 2-18b-15 = 0, B = - 1 or B = - 5 (rounding)
Answer: l: y = X-1
The maximum area is 2
