About the Course

Calculus is one of the grandest achievements of human thought, explaining everything from planetary orbits to the optimal size of a city to the periodicity of a heartbeat. This brisk course covers the core ideas of single-variable Calculus with emphases on conceptual understanding and applications. The course is ideal for students beginning in the engineering, physical, and social sciences. Distinguishing features of the course include: 1) the introduction and use of Taylor series and approximations from the beginning; 2) a novel synthesis of discrete and continuous forms of Calculus; 3) an emphasis on the conceptual over the computational; and 4) a clear, dynamic, unified approach. In this first part--part one of five--you will extend your understanding of Taylor series, review limits, learn the *why* behind l'Hopital's rule, and, most importantly, learn a new language for describing growth and decay of functions: the BIG O....

Very well structured for a refresher course. Thank you Professor Ghrist for your effort in putting this course together. A little additional outside research was required but well worth the effort.

Excellent class. Prof. Ghrist has a great teaching style, and his idea to use Taylor Series first is quite effective. Many functions I have shied away from in the past are now familiar to me.

Course is really cool, but oriented mostly on practical exercises and providing definitions. It would be much better if it had more formal proofs. Otherwise excellent course with a lot of challenging problems to solve.

It is a really good course, with a lot of definitions used at undergraduate level and well explained. Nevertheless, I could not understand too much about Big O. Probably, more examples would be useful to clarify it.

Would have preferred accompanying solutions. Just getting the answer ain't enough. Making sure my approach is correct is essential as well considering the course touches upon the absolute basics.

The course is intriguing. More practice questions and explanations will be good. And it will be beneficial if it can provide extra background knowledge (or link) for further study.

I quite enjoyed the course, although I found it unnecessarily tough sometimes. I believe extra solved examples for convergence, geometric and binomial series could help a lot!

思路上讲主线一直围绕泰勒级数展开,也总是以泰勒级数为思考角度(包括后面part 2也是如此),个人并不是十分适应这种纯数学的方式,更喜欢感官上、性质上来把握,所以……仁者见仁智者见智吧 ^_^

I have taken a calculus course at university which dealt with the epsilon-delta definition of things. Enjoyed the different approach as well, keep up the good work!

Challenging, because begins with the infinite series, which are not a simple concept. Once complete, a much higher level of mathematical understanding is achieved.

The order of growth lecture is extremely unclear and lacks sufficient information. Tt can be made more elaborate and a couple more examples would really help.

A good course but quire difficult and definitely requires a strong calculus foundation. The weird rhythm of the professor speaking is somewhat distracting.

High quality and entertaining videos. Correcting some organizational mistakes (like current links to textbook) would make this a five star class.

I would like to have been able to review some quiz questions with answers after the course was complete. That option does not seem to exist.

The lectures on Big O (growth rates) are way too hard to comprehend, compared to the rest of the lectures. Please do try to simplify them.

It was a nice course. Learned quite a bit about calculus. slides designes was awesome. love to complete other courses by prof. ghriest.

This is a very good course to understand the main theme of calculus. Though it was little bit hard I enjoyed the course.

Sometimes explanations are not complete enough to understand the problems. However, in general terms is a great course.

Excelente curso. Sugestão: maior número de exemplos resolvidos poderia facilitar a compreensão o estudante.

the big O part is a bit ubiquitous. But everything else is amazingly described.
