本書采用學(xué)生易于接受的知識(shí)結(jié)構(gòu)和英語表述方式,科學(xué)、系統(tǒng)地介紹了微積分(下冊(cè))中無窮級(jí)數(shù)、偏導(dǎo)數(shù)和二重積分、微分方程、差分方程等知識(shí)。強(qiáng)調(diào)通用性和適用性,兼顧先進(jìn)性。本書起點(diǎn)低,難度坡度適中,語言簡(jiǎn)潔明了,不僅適用于課堂教學(xué)使用,同時(shí)也適用于自學(xué)自習(xí)。全書有關(guān)鍵詞索引,習(xí)題按小節(jié)配置,題量適中,題型全面,書后附有答案。
本書可以作為大學(xué)數(shù)學(xué)微積分雙語或英語教學(xué)教師和準(zhǔn)備出國留學(xué)深造學(xué)子的參考書。特別適合中外合作辦學(xué)的國際教育班的學(xué)生,能幫助他們較快地適應(yīng)全英文的學(xué)習(xí)內(nèi)容和教學(xué)環(huán)境,完成與國外大學(xué)學(xué)習(xí)的銜接。本書在定稿之前已在多個(gè)學(xué)校作為校本教材試用,而且得到了師生的好評(píng)。
This book is intended to cover infinite series(Chapter 7), as well as
partial derivatives and double integrals(Chapter 8), differential equations(Chapter 9)
and difference equations(Chapter 10). The position of Chapter 7 is rather arbitrary.
Chapter 8 contains necessary background on vectors and geometry in 3space as well as
a bit of linear algebra that is useful, though not absolutely essential, for the
understanding of subsequent multivariable material.
The author has tried to write a textbook that is thoroughly modern and teachable,
and the capacity and needs of the student pursuing a first course in the Calculus have
been kept constantly in mind.
The text is designed for general calculus courses, especially those for business,
economics and science students.
Most of the material requires only a reasonable background in high school algebra and
analytic geometry.This book contains topics from which a selection naturally would be made
in preparing students for elementary work in applied science.We choose such subjects as
best suit the needs of our classes.
This book offers simple practical problems that illustrate the theory and at the same
time are of interest to the student.These problems do not presuppose an extended knowledge
in any particular branch of science,but are based on knowledge that all students of the
Calculus are supposed to have in common.
The expunging of errors and obscurities in a text is an ongoing and asymptotic process.
We will be grateful to any readers who call our attention, or give us any other
suggestions for future improvements.
