【種花家務(wù)·代數(shù)】1-6-10總復(fù)習(xí)題(代數(shù)第一冊(cè))『數(shù)理化自學(xué)叢書6677版』

2023-09-30 22:06 作者:山嵓  | 我要投稿

【閱前提示】本篇出自『數(shù)理化自學(xué)叢書6677版』,此版叢書是“數(shù)理化自學(xué)叢書編委會(huì)”于1963-1966年陸續(xù)出版,并于1977年正式再版的基礎(chǔ)自學(xué)教材,本系列叢書共包含17本,層次大致相當(dāng)于如今的初高中水平,其最大特點(diǎn)就是可用于“自學(xué)”。當(dāng)然由于本書是大半個(gè)世紀(jì)前的教材,很多概念已經(jīng)與如今迥異,因此不建議零基礎(chǔ)學(xué)生直接拿來自學(xué)。不過這套叢書卻很適合像我這樣已接受過基礎(chǔ)教育但卻很不扎實(shí)的學(xué)酥重新自修以查漏補(bǔ)缺。另外,黑字是教材原文,彩字是我寫的注解。

【山話嵓語】我在原有“自學(xué)叢書”系列17冊(cè)的基礎(chǔ)上又添加了1冊(cè)八五人教中學(xué)甲種本《微積分初步》,原因有二:一則,我是雙魚座,有一定程度的偶雙癥,但“自學(xué)叢書”系列中代數(shù)4冊(cè)、幾何5冊(cè)實(shí)在令我刺撓,因此就需要加入一本代數(shù),使兩邊能夠?qū)ε计胶猓欢t,我認(rèn)為《微積分初步》這本書對(duì)“準(zhǔn)大學(xué)生”很重要,以我的慘痛教訓(xùn)為例,大一高數(shù)第一堂課,我是直接蒙圈,學(xué)了個(gè)寂寞。另外大學(xué)物理的前置條件是必須有基礎(chǔ)微積分知識(shí),因此我所讀院校的大學(xué)物理課是推遲開課;而比較生猛的大學(xué)則是直接開課,然后在緒論課中猛灌基礎(chǔ)高數(shù)(例如田光善舒幼生老師的力學(xué)課)。我選擇在“自學(xué)叢書”17本的基礎(chǔ)上添加這本《微積分初步》,就是希望小伙伴升大學(xué)前可以看看,不至于像我當(dāng)年那樣被高數(shù)打了個(gè)措手不及。
