1.True or False (MUST WITH REASON OR COUNTEREXAMPLE): (a)Let {An} and {Bn} be two positive sequences and lim n→∞(An/Bn) exist. Then ΣAn comverges if and only if ΣBn converges. (b)Let ΣAn be a convergent series.Then lim n→∞An = 0. (c)Suppose that ΣA2n and ΣA2n+1 are convergent. Then ΣAn is alse convergent. (d)Suppose that ΣAn converges but ΣBn diverges. Then Σ(An+Bn) must be a divergent series. (e)A convergent sequence is always bounded. (f)If ΣAn converges,then Σ(-1)^n*An converges. (g)If both ΣAn and Σ(-1)^n*An converges,then Σ|An| converges. (h)If ΣAn converges,then ΣAn^2 converges. 2.Evaluate the area of the surface generated by rotating the curve x=e^t*cost,y=e^t*sint,0<=t<=2π about the X-axis. 3.Find the family of curves each of which intersects all of the hyperbolas xy=C at right angles. 4.Show that ∫a→b(x-a)(b-x)f''(x)dx = -2∫a→bf(x)dx if f is differentiable on [a,b] and f(a)=f(b)=0. 5.For what value of x does the series Σ(x-5)^n/(n*2^n) converges absolutely? Converges conditionally? Diverges? 6.Consider the curve C:r=sinθ,0<=θ<=π/4. (a)Find a parametric expression for the curve C in the XY-plane. (b)Find the arc length of C. (c)Find the volume of the solid by revolving the curve C with respect to the X-axis. -- ██◣ ███ █ ▊ █ █ ◣ █ █ ▇ █ █ http://www.wretch.cc/blog/sunnybright5 █ ◤ █ █ ▇ █████ ██◤ ███ █ ▊ █ █ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.113.64.4

panmike:別拿微積分刺激我 好大喜功,不意外 01/14 01:26
lo33:其實最近大家PO的文我都看不懂... 01/14 01:27
lo33:只能說我輸了... 01/14 01:29
mapleroyal:幹我讀一讀發現微積分沒救了,要過只能作弊了 01/14 01:31
panmike: 幹不要跟我提微積分,作弊嗨趴是三小 01/14 01:32
mapleroyal:幹反三角高中我都沒鳥她,雙曲函數又是三小 01/14 01:33
lo33:我們現在肛交到積分而已... 01/14 01:35
panmike: 幹強者我們老師提前交到下學期了啦超誇張 01/14 01:35
lo33:如果我期末不到50我也會被當...可是我有70分沒寫............ 01/14 01:41
iam066:噓第一題第二行的錯字.....這...我們還沒交道 01/14 01:58
dekacompt: 強者我們物理老師把大三的東西拿來教 01/14 01:58
kingdomL:我們習題士碩士班考題(菸 01/14 02:01
lucifiel1618:樓上不說我都不知道 01/14 03:19
kingdomL:我也是在為積分期末爆掉後才知道(菸 01/14 03:22
tom1990220:我比較想看台大的會計考題 01/14 09:58
mapleroyal:會計沒辦法PO啦,這次考CashFlow跟調整分錄 01/14 11:39
panmike:還是可以po啊只是畫表格比較麻煩 01/14 11:49
dekacompt:你可以請PANMIKE幫你畫XD 01/14 11:50
panmike:樓上有錢有閒還有官威可以洗版我怎麼比的上 01/14 12:17
tom1990220:一哥快po會計考題讓我瞻仰一下,話說我們還沒教cashflo 01/14 12:35
lucifiel1618: 錢有閒還有官威可以洗版我怎麼比得上by panmike GJ! 01/14 12:35
