Calculus made EASY! 5 Concepts you MUST KNOW before taking calculus!

CORRECTION - At 22:35 of the video the exponent of 1/2 should be negative once we moved it up!

Be sure to check out this video for an introduction to Calculus!

If you're ready for the actual calculus portion, then there's no better place to start than with this video here!


Thanks for the support!

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.

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.

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!

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.

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.

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.

My life would have gone in a very different direction if I had had learning resources like this in high school and college.

I learned more in 23 minutes than an entire semester

[mickdrummer]

Very nice, thank you. Am 75 and am just starting the ‘ math-physics’ journey.

"calculus" sounds like some kind of hard fungal infection...

[gregoryharlston]

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!

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.

Needed a refresher and this is by far one of the best explanations of most of the recurring concepts in calculus! Other videos just weren't as intuitive and I'm surprised this isn't more popular in the search results. You have a great sense for what needs to be explained right away, and what someone will learn through practice.

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!!!

[TranquilSeaOfMath]

A nice list of things students should look for in a precalculus course.

[Malladak]

This is great - I've spent weeks and weeks watching pre-cal videos to prep for college and in these 25 minutes I've grasp these concepts better than I've been able to since.

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
