    I'm 15 and watching 75 year old people study calculus really motivated me. 🙏
  • Thank you for this Dr. Ji. I am just beginning precalculus at age 74, and this clear teaching is just what i delight in.
  • @paulsccna2964
    The three pillars of Calculus, are Algebra, Trigonometry and Geometry. My advice is make sure your skills in each of these areas are ready for calc.
  • Correction - At 22:35 of the video the exponent of 1/2 should be negative once we moved it up!
  • @matthew80721
    Genius!! So many calculus videos assume previous knowledge. You've opened it up to people who don't have time to do uni but want a crash course on something interesting. Short and sweet, super easy to follow, well done.
  • @RtsFps1
    If anyone reads this i highly recommend watching this twice: before and 2-4 weeks into calculus. I’m taking calculus right now and this helps connect of uncertainties for me. Ty.

    After taking Calc, I'd suggest adding more trig stuff. Knowing your unit circle and its points and actually understanding how trig functions are related to each other is really important. Right after that would be a lot of the algebraic manipulation covered here.
  • I had a brain injury and am just restarting math after practicing law 30 years and having had a strong math background going into college 40 years. Dr Ji you are an excellent teacher. I’ve watched countless videos to try to reteach myself on the transition to calculus so I can try to master it with my rewired brain. You are superb. Thank you!
  • For those that care, there is an error at 22:36. The 1/2 exponent should be negative, -1/2, once the fraction has been inverted.
  • @Doing_Time
    "calculus" sounds like some kind of hard fungal infection...
  • Very nice, thank you. Am 75 and am just starting the ‘ math-physics’ journey.
  • I am an algebra teacher and I am impressed with the high quality of this video. You're clear, thorough, and unhurried! You've given me a model and target to aim for! Well done!
  • @CBWMSJR
    Okay. He has gift. He can teach without inflicting pain. Haven't looked at this stuff for 40 yes and answered questions I didn't even know I had. Good job
  • Thank you so much for this video. This has greatly helped my understanding in Calculus. I cannot stress how lost I was in my college Calculus 1 class, looking at the board and being absolutely confused. You are a godsend... I hope your channel blows up and you succeed!
  • @JustWilson
    This was so helpful as a refresher before uni. I’ve always found maths hard because teachers over complicated things and didn’t properly explain their relationships to one another. This cleared up so many concepts I’ve been stuck on, thank you!
  • @RCBIGFLYER1
    I don"t know why my math teachers did not explain things like you do. You are a good teacher, Dr. Ji!
  • A nice list of things students should look for in a precalculus course.
  • @RetroS01
    This is the most simple, quick, to the point, informative video I have ever come across for calculus. I would LOVE if you made a Calc B, C, and D versions of these kinds of videos. Subscribed!!!
