Calculus · Interactive course

按《普林斯顿微积分读本》的章节顺序与教学节奏做成的互动课页——不是译本,不是大纲占位。讲解、例子、练习全部原创,关键术语给英文。每章有可拖的图、例题和答案。
给港科广 BEng(AI) 用:先把单变量微积分站稳,再接到一年计划里的概率、优化、随机过程。不走视觉。

Interactive pages that follow the chapter order and teaching pace of The Calculus Lifesaver — not a translation dump, not an outline placeholder. Explanations, examples, and drills are original. Every chapter has a figure you can drive, plus worked examples.
Built for HKUST(GZ) BEng(AI): get single-variable calculus standing, then plug into the year plan’s probability, optimization, and stochastic processes.

00怎么用这套课

对照 Banner 的书读,不要当书的替代品。书负责细节和题量,这套课负责把每一章的几何直觉做成能拖的东西——卡住了先来对应章,看「一分钟结论」和互动台。

必啃的 10 章是骨架:极限、连续可导、求导、指数对数、最优化、定积分、基本定理、级数、泰勒、微分方程。标「解题」的章是 Banner 原书里的 How-to 章——可以快过,但不要空着跳,里面是手艺不是新概念。

版权一句 本课对标该书目录与节奏,不摘录 Banner 原文或中译段落。可以说「对照第 X 章」,不能拿它当电子书。

每章固定长这样

整套课按「先直觉,后形式化」重排过一次。每一章打开都是同一个顺序,扫一眼就知道自己在哪:

位置它替你回答什么
人话(大字卡片) 这一章一句话是什么。放在最前面,先给直觉再给定义。
一张图 把这一章的核心画成一张图。图比文字快。
本章关键词 3–5 个新术语,各配两三个字的直觉。读到后面遇上时脑子里有挂钩。
完整结论(折叠) 原来那段密集的要点收进了折叠框,复习时看,初学可以先跳过
常见死法 讲完一个概念就说清大多数人在这里会怎么错,以及正确动作是什么。
互动台 + 观察指引 每个可拖的实验前面都有三个先自己答的问题。没有指引的互动,拖完就忘。
AI 接口 固定在例题之前一节,标着绿色 AI 接口 芯片。回答「这一章跟我做的事有什么关系」。
例题 · 先想 30 秒 题干和解答之间插了一句引导。先自己想过再看解答,得到的是判断力,不是一条你没想到的路径。
练习 / 术语 / 对照 五段式习题、中英术语速查、和 Banner 原书的逐节对照。
和学校课、一年计划怎么叠 Q1 学校有 UFUG1105 Honors Calculus I(单变量)。一年计划里写过:自学部分不重复微积分——这套课就是学校课的互动对照本,不是再开一门平行课。Q2 要提前补的是 18.02 多元(梯度 / Jacobian / 拉格朗日),那是下一层,不在 Banner 这本书里。

00How to use this course

Read it against Banner’s book. Do not treat it as a replacement. The book owns detail and drill volume. These pages own the geometric intuition of each chapter, made draggable — when you stall, open the matching chapter, read the one-line takeaway, and use the lab.

The 10 chapters marked must are the skeleton: limits, continuity/differentiability, differentiation, exp/log, optimization, definite integrals, FTC, series, Taylor, ODEs. Chapters marked “drill” are Banner’s How-to chapters — you may go fast, but do not skip them empty; they are craft, not new ideas.

Copyright, one line This course tracks the book’s table of contents and pace. It does not excerpt Banner’s prose or the Chinese translation. You may say “see Chapter X”; you may not treat this as an ebook of the book.

Every chapter is built the same way

The whole course was rearranged as intuition first, formalization second. Open any chapter and the order is identical:

SlotWhat it answers
In plain wordsThe one sentence of the chapter. First, before definitions.
One figureThe core of the chapter drawn as one picture.
Key words3–5 new terms, each with a two-to-four-word hook.
Full recap (folded)The dense bullet list, for review; skip on first read.
Common deathsRight after a concept: how most people get this wrong, and the correct move.
Lab + watch listThree questions to answer yourself before you drag.
AI hookAlways the section before the examples. Answers “what does this have to do with what I build?”
Example · Think 30 secondsA prompt between stem and solution. Think first.
Drills / terms / BannerFive-tier exercises, EN/ZH glossary, section map to the book.
How this stacks with school and the year plan Q1 school has UFUG1105 Honors Calculus I (single-variable). The year plan already said: self-study does not redo calculus — this course is the interactive companion to the school class, not a parallel course. What you must add yourself in Q2 is 18.02 multivariable (gradient / Jacobian / Lagrange). That is the next layer; it is not in Banner.

02三条学习路线

路线 A跟书走完全程(推荐,约 10–14 周)
第 1 章 → 第 30 章按序。解题章(4 / 6 / 18–19 / 21 / 23 / 25–26)周六做题时用,平日先把必啃章的互动拖一遍。
路线 B只走骨架(约 4 周,对接 Honors Calc I)
1 函数 → 3 极限5 连续可导6 求导9 指数对数13 最优化 / 线性化 → 15–16 积分 → 17 基本定理22 级数24 泰勒30 微分方程
学校课讲到哪一章,就打开对应页当实验台。
路线 C为后面的概率 / 优化预热(约 10 天)
5 可导定义(后面梯度是它的高维版)→ 9 $e^x$ 与 $\ln$(交叉熵、softmax 的零件)→ 13 线性化与最值(梯度下降的一维原型)→ 16–17 定积分与 FTC(连续期望 $\mathbb{E}[X]=\int x f(x)\,dx$)→ 22 级数(特征函数、生成函数的直觉)→ 24 泰勒(任何局部二次模型)→ 30 微分方程(随机微积分的确定性前身)。

02Three routes

Route AWalk the whole book (recommended, ~10–14 weeks)
Chapter 1 → 30 in order. Use the drill chapters (4 / 6 / 18–19 / 21 / 23 / 25–26) on problem Saturdays; on weekdays drag the must-chapter labs first.
Route BSkeleton only (~4 weeks, pairs with Honors Calc I)
1 functions → 3 limits5 continuity / differentiability6 differentiation9 exp / log13 optimization / linearization → 15–16 integrals → 17 FTC22 series24 Taylor30 ODEs.
Wherever the school class is, open that page as the lab bench.
Route CWarm-up for probability / optimization (~10 days)
5 definition of the derivative (later gradients are the high-dimensional version) → 9 $e^x$ and $\ln$ (parts of cross-entropy and softmax) → 13 linearization and extrema (1-D prototype of gradient descent) → 16–17 definite integrals and FTC (continuous expectation $\mathbb{E}[X]=\int x f(x)\,dx$) → 22 series (intuition for characteristic / generating functions) → 24 Taylor (any local quadratic model) → 30 ODEs (deterministic precursor of stochastic calculus).

03它在一年计划里的位置

时间一年计划在干什么这套微积分课干什么
Q1 · 9–11 月主课是 6.041 概率;学校同步 Honors Calc I 当学校课的互动笔记本。优先必啃章。积分(16–17)要在连续随机变量之前心里有数。
Q2 · 12–2 月18.650 统计 + EE364a 凸优化 + 18.02 多元三块 单变量必须已经不挡路:链式法则、泰勒、最值。多元从本课的第 6 / 13 章长出去,不在本课范围内。
Q3–Q4随机过程、Itô(应用层)、后训练目标函数 第 22 / 24 / 30 章是复用零件:级数、局部多项式、微分方程。用到再回看,不必重刷全书。
和 18.06 教程的关系 视觉语言、导航、一章一页、练习折叠答案——同一套皮肤。线代已经完成(34 讲)。微积分是下一件公开制品。

03Where this sits in the year plan

WhenYear planThis calculus course
Q1 · Sep–NovMain course 6.041 probability; school Honors Calc I in parallel An interactive notebook for the school class. Prioritize must-chapters. Integrals (16–17) should be in your head before continuous random variables.
Q2 · Dec–Feb18.650 stats + EE364a convex opt + three blocks of 18.02 Single-variable must not be a blocker: chain rule, Taylor, extrema. Multivariable grows out of chapters 6 / 13; it is out of scope here.
Q3–Q4Stochastic processes, Itô (applied layer), post-training objectives Chapters 22 / 24 / 30 are reusable parts: series, local polynomials, ODEs. Revisit when you need them; do not re-grind the book.
Relation to the 18.06 course Visual language, navigation, one-page-per-lecture, folded answers — the same skin. Linear algebra is done (34 lectures). Calculus is the next public artifact.

04关于目录的声明

诚实标注 章名中英对照来自 Banner, The Calculus Lifesaver(Princeton, 2007)目录,以及人民邮电《普林斯顿微积分读本(修订版)》中译目录。附录 A「极限及其证明」、附录 B「估算积分」按原书附录收录。若你手上的版本分节编号有出入,以纸书目录为准,本课按章对齐。

04A note on the table of contents

Labeled honestly Chinese/English chapter names follow Banner, The Calculus Lifesaver (Princeton, 2007), and the Posts & Telecom Chinese edition. Appendix A “Limits and Proofs” and Appendix B “Estimating Integrals” follow the book’s appendices. If your print edition numbers sections differently, the paper TOC wins; this course aligns by chapter.
