令s=1-3+3^2-3^3+3^4-3^5+……-3^99+3^100
-3s=-3+3^2-3^3+……+3^100-3^101
相减,中间相同的减去了
-3s-s=-3^101-1
所以4s=3^101+1
s=(3^101+1)/4

well,
i should say no
honesty should be everyone's principle,
but it's not any time or any where right!
for example,
a dying patient is in hosipital,
almost no doctors will tell him he is sure to be death soon.
another example,
when a 5-year-old child ask his parents how he came,
his parents will never say 'you came from our making love...' untill the child is much older.
so i don't think peopl should always tell the truth,
only depends~

Yes. Because music and art can both stand for the best of the human culture. A man without any knowledge of music or art will not be able to understand our civilization well, thus lose an important spirit of the human species.

也就是说,水箱上部还剩下 1 分米的空间没有装满水.则这部分的容积：
V = 6 * 5 * 1 = 30 (dm^3)
铁块的体积 V' = 4 * 4 * 4 = 64 (dm^3)
可见,因为 V'>V,所以只要把铁块放进水箱中,则水箱中的水肯定会溢流出来.

Tour.
Tour can increase our knowledge.

cos(225度) = -根号2 /2
sin（25π/6） = 1/2
sin(-17π/3) = 根号3 /2
tan(-32π/3) = 根号3
sin85°= cos5°
cos（2/5 π）= sin（1/10 π）
tan（π/3）= cot(π/6)
sin a - cos a=1/5
1-2sinacosa=1/25
24/25=2sinacosa
12/25=sinacosa
sin^3 a - cos^3 a
= (sina-cosa)((sina-cosa)^2+3sinacosa)
= (1/5)((1/5)^2+3*12/25)
= 37/125
sin^4 a - cos^4 a
= (sin^2 a + cos^2 a)(sin^2 a - cos^2 a)
= 1*(sin a + cos a)(sin a - cos a)
= 正负根号(1+2cosasina)*1/5
= 正负根号(49/25)*1/5
= 正负7/5*1/5
= 正负7/25

obvious ur parents and friends will tole u the right information.

1.正方体一个面的面积=72/2=36
长方体表面积=36*10=360 （每个正方形少一个面）
36=6*6 则长方体的长=6+6=12
长方体体积=6*6*12=432
2.48/2=24 99/3=33 352/4=88
（24+33+88）*2=290
3.表面积=(30+20+24)*2=148
30与20的最大公因数是5,20与24的最大公因数是4,24与30的最大公因数是6
体积=5*4*6=120
4.20*10*5=1000
1000/8=125 （8个小正方体拼一个大正方体）
5.正方体边长=4+2=6,正方体体积=6*6*6=216,
剩余长方体边长=（120/4）/6=5 剩余长方体体积=6*6*5=180
原长方体体积=216+180=396

After being an English teacher for eight years,I finally made some change of my life.I came into doing foreign business in a trade company.I found the job in the personnel market where I compete with many other people who have just or have not graduated from college.I am much lower paid now than when I was a teacher.But I don't complain.Life should be much colorful.And I will always try my best.

这是练习册第39页的题目,答案是150立方厘米的解法是对的.

应用
①水的比热较大,对于气候的变化有显著的影响.在同样受热或冷却的情况下,水的温度变化小一些,水的这个特征对气候影响很大,白天沿海地区比内陆地区温升慢,夜晚沿海温度降低少,为此一天中沿海地区温度变化小,内陆温度变化大,一年之中夏季内陆比沿海炎热,冬季内陆比沿海寒冷.
②用热水取暖,冬季供热用的散热器、暖水袋.
③用水冷却汽车的发动机,发电厂的发电机等.
④农村在培育秧苗时,为保护秧苗夜间不致受冻,傍晚要往秧田里灌水,夜间秧田里温度不致降的太多,秧苗不致冻坏,早晨再把水放出去,以日照使秧苗温度高一些,有利于生长.
