Mathematician Grant Sanderson opened a Youtube channel in 2015, and since then, he has been making amazing math videos to bring a visual perspective on teaching higher mathematics.

For instance, he made 12 free, utterly valuable calculus lectures on Youtube and put them on a playlist called “**Essence of Calculus.**” In that video series, he only covers calculus’s core ideas and gives us all the necessary information to “invent calculus” ourselves. Grant Sanderson’s easy-to-understand visual approach makes you feel like calculus is something that you could have discovered yourself.

“Essence of Calculus” is the visual introduction to the core ideas of derivatives, integrals, limits, and more. These twelve calculus lectures are a treasure for every math learner and make learning calculus intuitive and fun!
