1、數(shù)學(xué)分析專題研究期末試題一、 填空題（每小題3分，共18分）1.若，則.2.若，則.3.設(shè)，若，有,則稱為從到上的 .4.含有 的等式叫做函數(shù)方程.5.設(shè)，則.6.設(shè)函數(shù)定義在開區(qū)間內(nèi)，對于，有，則稱是內(nèi)的 函數(shù).二、 單項選擇題（每小題3分，共18分）1.設(shè)，有.a. b. c. d. 2.自然數(shù)集，是（ ）a. 有限集 b. 可列集 c. 不可列集 d. 空集3.設(shè)定義在上，是的極小值點，則（ ）a. b. 有 c. 當時，有d. 4.設(shè)是二元函數(shù)，且使得，則函數(shù)是（ ）a.有理函數(shù) b. 無理函數(shù) c. 代數(shù)函數(shù) d. 超越函數(shù)5.設(shè)是內(nèi)的嚴格上凸函數(shù)，則（ ）a. 在內(nèi)必取到最大值 b

2、. 在內(nèi)必取到最小值c. 在內(nèi)有 d. 前三個結(jié)論都不對6. 在內(nèi)連續(xù)可導(dǎo)，且，使得，則是（ ）a. 穩(wěn)定點 b. 極值點 c. 拐點 d. 臨界點三、 計算題（每小題6分，共24分）1.設(shè)，求.2.已知的曲線經(jīng)過點，且曲線上任意點的切線的斜率是該點橫坐標的2倍，求.3.已知，求.4.已知，求.四、 證明題（每小題8分，共32分）1.設(shè)定義在上，對于任意的，有，則是常值函數(shù).2.證明（1） (4分)(2) （4分）3.若函數(shù)在閉區(qū)間上連續(xù)，且皆屬于，則至少存在一點，使得4.設(shè)證明答案：一、 填空題（每小題3分，共18分）1、；2、甲，乙，甲，乙；3、單射；4、未知函數(shù)；5、；6、上凸。二、 單

3、項選擇題（每小題3分，共18分）1.d;2.b;3.c;4.c;5.d;6. a.三、計算題（每小題8分，共32分）1.解 因為,故有 5分所以有 8分2.解由方程可得，由得，即 8分3.解 已知，對兩端關(guān)于求導(dǎo)，得 4分由 8分4、解 已知 （1）令，即，得 （2）（2）得 6分 即， 8分四、證明題（每小題8分，共32分）1、證明：對于，有 令，則得， 6分由的任意性知，。 8分2、證明：用表示的補集，則（1） = = 4分（2） = = 8分3、已知在上連續(xù)，故在有最大值與最小值，從而有 4分由介值定理，存在，使 8分4設(shè)，對于，我們有，即在內(nèi)是嚴格下凸函數(shù)，故對于有 6分代入得 8分i
