答案:,,所以,這樣。/star3/origin/33c60b2097dd54b093880beb3ee2b5c4.png

答案:(1)因?yàn)?,;所以,在處函數(shù)連續(xù)。又因?yàn)?,;所以函數(shù)在處不可導(dǎo)。(2),且,所以在處連續(xù)。這個(gè)極限不存在,所以在處不可導(dǎo)。/star3/origin/f1ceb0a2382c1229f0782f77ac6a5b7b.png

答案:連續(xù),且有一階導(dǎo)數(shù)/star3/origin/1c359c8468e00f97b8cfdd798ef72552.png

答案:,、為任意常數(shù)/star3/origin/5bb9c92a3efefbbf37a0f54ecacb42d9.png

答案:由,聯(lián)立得交點(diǎn).面積;體積/star3/origin/e7fceda6e1afe640e52ad22c6d519128.png

答案:(發(fā)散)/star3/origin/4a147bbd2942227e30ded42dcef07df7.png

答案:先求駐點(diǎn):,解得:,形成個(gè)駐點(diǎn)。又由于:,可知:可得:函數(shù)在取極大值,在這四點(diǎn)去極小值。/star3/origin/85aa92980b121127e6b3c13749d5ac63.png

答案:設(shè)點(diǎn),則:(1)時(shí)故設(shè):,題目所求距離即為最小值可得唯一駐點(diǎn)及唯一極值點(diǎn),即為題目所求最小值點(diǎn)故代入得
