The feeling of helping parents do housework More than 300 words, urgent

On Saturday, I woke up early. Lying in bed, I recalled the teacher's words: "after I go home, I must help my parents do housework and repay what my parents usually do for us." I continued to recall everything my mother did for me. It was so hard. I thought about it. My mother usually had to go to work, and she came back in the afternoon to do housework and help me

The feeling of doing housework for mom on March 8

Every day, my mother is very tired at work, and I have to do housework when I get home. It's too hard. On March 8, women's day, I want to do something for my mother and give her a surprise!
Early, I came home, no longer as usual, sitting on the sofa to nibble at the apple, but to take the broom, squeeze the mop to clean every room in the house
I came to the living room and looked around. The floor under the "Big Mac" sofa was really hard to deal with, but no matter how hard it was for my mother's holiday, it would have to be completed. With the combination of my wisdom and physical strength, the floor of the living room was as shiny as new. Then, the dust in the big room, small room, dining room and kitchen became my losers, After that, with the help of dishcloth and brightener, all the furniture in the house was completely new. Finally, I straightened up and took a deep breath. Alas, housework is really tiring
I think, mother's surprise should be more than that, tomorrow morning I will let my mother be a lucky woman! I will quietly get up before my mother, prepare western breakfast, let the sliced bread mixed with jam smile to my mother, let the fragrant hot coffee arouse my mother's appetite, let the bright sun egg sunshine my mother's mood
I seem to have seen my mother's dimple with a sweet smile, in this festival, I sincerely wish my mother happy and happy!

Experience of helping mother do housework
I want to help my mother do housework, cooking, shopping, dishwashing, cleaning, washing clothes and so on, and then put my experience down. It's in our fifth grade "happy winter vacation" exercise book. Just write 2 or 3 sentences. Or 30-60 words is OK

After this experience of helping my mother do housework, I found that my mother is so hard at home, and I often quarrel with her, which is really inappropriate. At the same time, I found that occasionally doing housework can exercise our will, so I decided to spare some time every week to help my mother do housework

Find the limit (1 + 1 / x) ^ (x ^ 2) / (e ^ x)
The limit drawn by the Geometer's Sketchpad should be 1 / E,

Is LIM (x →∞) [(1 + 1 / x) ^ (x ^ 2)] / (e ^ x)
= = = = = = = = =
Let y = [(1 + 1 / x) ^ (x ^ 2)] / (e ^ x),
Then ln y = (x ^ 2) ln (1 + 1 / x) - X
Let t = 1 / X,
Then when x →∞, t → 0
And x = 1 / T
So LIM (x →∞) ln y
=lim (t→0) ln (1+t) /(t^2) -1/t
=lim (t→0) [ ln (1+t) -t ] /(t^2).
According to the law of lobita,
lim (t→0) [ ln (1+t) -t ] /(t^2)
=lim (t→0) [ 1/(1+t) -1 ] /(2t)
=( -1/2) lim (t→0) [ 1 /(1+t) ]
= -1/2.
So LIM (x →∞) ln y = - 1 / 2
So the original formula = LIM (x →∞) y
= e^(-1/2).
= = = = = = = = =
The above calculation may be wrong
Find the limit of y = f (x) ^ g (x),
->Find ln y
->Using t = 1 / x, the ∞ - ∞ type is reduced to 0 / 0 type
->The law of lobida
->The limit of LN y is obtained
->Find the limit of Y

It is known that line L is tangent to circle x2 + Y2 + 2x = 0 at point t, and intersects hyperbola x2-y2 = 1 at two points a and B. If t is the midpoint of line AB, the equation of line L is obtained

Let the equation of l be & nbsp; X = KY + A, and substitute it into hyperbolic equation & nbsp; to get (k2-1) Y2 + 2kay + A2-1 = 0. & nbsp; & nbsp; and k2-1 ≠ 0, then y & nbsp; Let't = YT = KYT + a = - ak2 − 1, that is, t (A1 − K2, AK1 − K2) · (t (A1 − K2, AK1 − K2) · (t point t in the circle, {(AK1 + YB2) 2 + (A1 − K2) 2 + (A1 − K2) 2 (A1 − K2) 2 + (A1 − K2) 2 + 2 + 2A1 + 2A1 − K2 = 0, that is, let't = 2, from the center o '(-1,0, O' (-1,0,0), o't \\\\\\\\\\\\\\\\\\\\nbsp; X = - 2; when K2 = 2A + 1, the equation of & nbsp; a = 1K = ± 3, l is x = ± 3Y + 1, so the equation of line L is x = - 2 or & nbsp; X = ± 3Y + 1

Solution equation: x + 7 / 15 = 11.2.5x + 2 / 5 = 1.6.5x + 1 / 5 = 11 / 5-4-x = 1 / 6

x+7/15=11/30 2.5X+2/5=1.6 5X+1/5=11/5
X=11/30-7/15 2.5X=1.6-2/5 5X=11/5-1/5
=11/30-14/30 X=1.2 ÷ 2.5 X=2/5
=-1/10 =12/25
4/5-X=1/6
X=4/5-1/6
