My style of teaching calculus is very visual and dynamic. My hope is that these videos will make things clear to you in a way that a static book cannot. I want to help you see what the ideas are behind the things that are ordinarily taught in calculus. If you can get that, you will have a much better chance of remembering what you learned and also of knowing how to use it. The videos will help you learn the techniques, too, but we will always strive to see why these things make sense. Despite what you may have heard (or, if you’ve studied calculus already, what you may have experienced), calculus is a very sensible subject, based on many things that you already understand through your own observations of the world.

At this point, the videos on the Making Sense of Calculus page don’t quite start from the beginning. So, if you are brand new to calculus, I’m afraid you’ll have to wait a bit until I can make the first few introductory videos. But for those of you who’ve had some calculus, I think you’ll already find some fresh ways of looking at some of the things you’ve learned. Please do let me know what you think!





  1. Dennis,

    I think your work is fantastic, and look forward to my son benefiting from your work and others contributing to Ted Ed, Kahn Academy…

    I just viewed your “Infinity” video this morning, and wondered if would you be open to a brief discussion about how you made it? Or, an email exchange if that’s more convenient for you.

    I need to make several videos about several complex topics, such as the credit assignment problem, correlation vs causation, true experiments, and so on. I’m very interested in how you worked with an agency to communicate such a complex topic. For example, what roles or individuals provided the most substantive help (was it the copy writer?), how you ‘briefed’ them (did you provide a prototype?), how you edited to arrive at the final story (did you user test?), etc.

    I promise to keep it brief. I’m just hoping to learn a bit from your experience before plunging in blindly.
    Kelly C.

  2. Thanks, Kelly! I’ll send you email so we can discuss your questions.

  3. Your videos are fantastic! Thanks so much…I emailed my older son who is 16 to remind him to not forget to see these when he needs to learn calculus.
