學生對 宾夕法尼亚大学 提供的 Calculus: Single Variable Part 1 - Functions 的評價和反饋

Amazing course! I took Calc 1 and 2 way back when and plan to attend college again starting this summer to earn another degree. Being Engineering, I wanted to brush up on my calc 1 and 2 before I dive into DiffEQs and Linear Algebera and this course did just that for me. The best part about it was that he assumes you alerady have a basic understanding of the material so its not like starting from square 1.

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.

As I already have my Mathematics Minor, I wanted a quick refresher course. I would say this course is severely lacking in both practice problems as well as example problems done during video sessions. Students need more applied concepts to be able to understand and succeed if this content is not familiar. I got by only by preexisting knowledge of these Math concepts.

Excellent course from a great school and excellent professor. The videos were informative. I found this class to be very challenging. I ended up with an A and look forward to the next parts. I think you need some exposure to calculus before taking this class. I took calculus 8 years ago.

Ghrist makes math fun by putting a twist on the lessons. It may look childish/cartoonish, but Ghrist obviously understands what younger people well.

Interesting approach to start a calculus lesson. I liked it very much although I can understand that some people dislike the steep learning curve. On the other hand it was stated from the beginning that this is a tough course. Summarized I learned a trick or two for which I am grateful. Thanks! Lastly there are active mentors in this course that are very helpful. Overall the course is very recommendable for advanced and curious calculus students.

Enjoyed the whole journey in this course. Beautiful graphics, choir-base-like sound, concise explanation and instrumental exercises. Thanks Prof. Ghrist.

Great course! Material is really dense and highly practical. Thanks!

Interesting starting point for calculus which makes intuitive sense. The visuals in the lectures are excellent, specifically on the explanation of limits. Taking this course is akin to reading a spy thriller book, the farther one goes the more intriguing it gets.

Great one.

Teacher Ghrist is good at providing thought-provoking insight and visualization of basic function, math formula as well as series expansion.

In addition, this course starts with a set of basic functions and domain knowledge such as simple polynomial, trigonometric, exponential, natural log, hyperbolic trigonometric, simple derivative and integral, and so on.

Then we will go through Taylor series and its expansion. To be honest, Taylor series as well as expansion is the key essential part of this course, it is not only useful for us to evaluate function value and its error of a given point, but also practical to get better understanding of limitation within 0/0 and ∞/∞ as well as L'Hospital's Rule later.

Finally, this course ends with analysis of function growth rate, upper bound of function when it comes to zero point or infinity, and the application of L'Hospital's Rule.

It is strongly recommended taking this course to start our wonderful calculus journey.

wonderful experince

One of the great course which helps me to Revise and also fill the missing topics

This course, which teaches calculus, assumes that the audience already knows calculus. That's so ridiculous!

Not worth it - better to just read a book on calculus, as the homework questions at the end of each session does not even reflect one single example in the 16min session. Disappointed, but then again what can you learn in 15 min sessions, very little.

Great course! A particularly novel and extremely well-done presentation of the basics of calculus, part of a multi-course sequence that covers the whole of single variable calculus. Also worth a serious look is Professor Ghrist's material on multivariate calculus, available on You Tube. See his Penn web site for more details (http://www.math.upenn.edu/~ghrist/).

I appreciated the in depth theory and mechanics.

This is a much more in-depth calc class than I've had at univ, and by more in-depth I mean it's harder. That being said I feel like I understand the material better as before there was much more memorization whereas this has more explanation. A++++++ would take again.

Great UI and explanation.Started with the Engg. maths and taking it to high school and for the Developer like me Big O is something which introduced in a appropriate way..:)

It's a very good course that uses a different point of view to understand how things works in calculus. It's very didatic and helps you think outside the box. If you're thinking about do the course, keep in mind that it is necessary previous knowledge in calculus.

Challenging but fascinating.

This was great, thank you! The only thing that would be useful is solutions to missed problems after the assignment has been completed because it's hard to know what you did wrong when you are working by yourself.

I THINK THIS IS VERY HELPFUL FOR ME.THANKS FOR TEACHER'S TEACH AND COURSERA'S FAVOUR.

Excellent course. A little bit of toughness but quite enjoyable and rewarding.

best math course i've had so far after long years out of school~ thanks!
