1、微積分初步形成性考核作業(yè)(一)解答函數(shù),極限和連續(xù)一、填空題(每小題2分,共20分)1函數(shù)的定義域是解:, 所以函數(shù)的定義域是2函數(shù)的定義域是 解:, 所以函數(shù)的定義域是3函數(shù)的定義域是解: , 所以函數(shù)的定義域是4函數(shù),則 解: 所以5函數(shù),則 解:6函數(shù),則 解:,7函數(shù)的間斷點(diǎn)是 解:因?yàn)楫?dāng),即時(shí)函數(shù)無(wú)意義 所以函數(shù)的間斷點(diǎn)是8解:9若,則解: 因?yàn)?所以10若,則解:因?yàn)?所以二、單項(xiàng)選擇題(每小題2分,共24分)1設(shè)函數(shù),則該函數(shù)是()a奇函數(shù) b偶函數(shù)c非奇非偶函數(shù) d既奇又偶函數(shù)解:因?yàn)?所以函數(shù)是偶函數(shù)。故應(yīng)選b2設(shè)函數(shù),則該函數(shù)是()a奇函數(shù) b偶函數(shù)c非奇非偶函數(shù) d既奇又

2、偶函數(shù)解:因?yàn)?所以函數(shù)是奇函數(shù)。故應(yīng)選a3函數(shù)的圖形是關(guān)于()對(duì)稱a b軸c軸 d坐標(biāo)原點(diǎn)解:因?yàn)?所以函數(shù)是奇函數(shù) 從而函數(shù)的圖形是關(guān)于坐標(biāo)原點(diǎn)對(duì)稱的 因此應(yīng)選d4下列函數(shù)中為奇函數(shù)是()a b c d解:應(yīng)選c5函數(shù)的定義域?yàn)椋ǎ゛ b c且 d且解:,所以應(yīng)選d 6函數(shù)的定義域是()a bc d解:,函數(shù)的定義域是,故應(yīng)選d 7設(shè),則( )a b c d 解: ,故應(yīng)選c8下列各函數(shù)對(duì)中,()中的兩個(gè)函數(shù)相等 a, b, c, d, 解:兩個(gè)函數(shù)相等必須滿足定義域相同函數(shù)表達(dá)式相同,所以應(yīng)選d9當(dāng)時(shí),下列變量中為無(wú)窮小量的是( ).a b c d解:因?yàn)椋援?dāng)時(shí),為無(wú)窮小量,所以應(yīng)選

3、c10當(dāng)( )時(shí),函數(shù),在處連續(xù).a0 b1 c d 解:因?yàn)椋?若函數(shù),在處連續(xù),則,因此。故應(yīng)選b11當(dāng)( )時(shí),函數(shù)在處連續(xù).a0 b1 c d 解:,所以應(yīng)選d12函數(shù)的間斷點(diǎn)是( )ab c d無(wú)間斷點(diǎn)解:當(dāng)時(shí)分母為零,因此是間斷點(diǎn),故應(yīng)選a三、解答題(每小題7分,共56分)計(jì)算極限 解:2計(jì)算極限解:3 解: 4計(jì)算極限 解:5計(jì)算極限解:6計(jì)算極限 解: 7計(jì)算極限解: 8計(jì)算極限 解: 微積分初步形成性考核作業(yè)(二)解答(除選擇題)導(dǎo)數(shù)、微分及應(yīng)用一、填空題(每小題2分,共20分)1曲線在點(diǎn)的斜率是 解:,斜率2曲線在點(diǎn)的切線方程是 解: ,斜率 所以曲線在點(diǎn)的切線方程是:3曲

4、線在點(diǎn)處的切線方程是解:,斜率 所以曲線在點(diǎn)處的切線方程是:,即:4 解:5若y = x (x 1)(x 2)(x 3),則(0) = 解:6已知,則=解:,7已知,則=解:,8若,則 解:, 9函數(shù)的單調(diào)增加區(qū)間是 解:,所以函數(shù)的單調(diào)增加區(qū)間是10函數(shù)在區(qū)間內(nèi)單調(diào)增加,則a應(yīng)滿足 解:,而,所以二、單項(xiàng)選擇題(每小題2分,共24分)1函數(shù)在區(qū)間是( d )a單調(diào)增加 b單調(diào)減少c先增后減 d先減后增2滿足方程的點(diǎn)一定是函數(shù)的( c ).a極值點(diǎn)b最值點(diǎn) c駐點(diǎn)d 間斷點(diǎn)3若,則=(c ) a. 2 b. 1 c. -1 d. -24設(shè),則(b ) a b c d5設(shè)是可微函數(shù),則( d )

5、 a b c d 6曲線在處切線的斜率是( c ) a b c d 7若,則( c ) a b c d 8若,其中是常數(shù),則( c ) a b c d9下列結(jié)論中( b )不正確 a在處連續(xù),則一定在處可微. b在處不連續(xù),則一定在處不可導(dǎo). c可導(dǎo)函數(shù)的極值點(diǎn)一定發(fā)生在其駐點(diǎn)上. d若在a,b內(nèi)恒有,則在a,b內(nèi)函數(shù)是單調(diào)下降的.10若函數(shù)f (x)在點(diǎn)x0處可導(dǎo),則( b )是錯(cuò)誤的 a函數(shù)f (x)在點(diǎn)x0處有定義 b,但 c函數(shù)f (x)在點(diǎn)x0處連續(xù) d函數(shù)f (x)在點(diǎn)x0處可微 11下列函數(shù)在指定區(qū)間上單調(diào)增加的是( b) asinx be x cx 2 d3 - x12.下列結(jié)

6、論正確的有( a ) ax0是f (x)的極值點(diǎn),且(x0)存在,則必有(x0) = 0 bx0是f (x)的極值點(diǎn),則x0必是f (x)的駐點(diǎn) c若(x0) = 0,則x0必是f (x)的極值點(diǎn) d使不存在的點(diǎn)x0,一定是f (x)的極值點(diǎn)三、解答題(每小題7分,共56分)設(shè),求 解:2設(shè),求.解:3設(shè),求.解:4設(shè),求. 解:5設(shè)是由方程確定的隱函數(shù),求.解:兩邊微分: 6設(shè)是由方程確定的隱函數(shù),求. 解:兩邊對(duì)求導(dǎo),得: , 7設(shè)是由方程確定的隱函數(shù),求.解:兩邊微分,得: ,8設(shè),求解:兩邊對(duì)求導(dǎo),得: 微積分初步形成性考核作業(yè)(三)解答(填空題除外)不定積分,極值應(yīng)用問(wèn)題一、填空題(
