The essence of calculus
3Blue1Brown
The first video of 3Blue1Brown's Essence of Calculus series, which builds toward integrals, derivatives, and the fundamental theorem of calculus from a simple geometry question. It aims to make viewers feel they could have invented calculus themselves.
A staple recommendation for anyone learning math, praised for visual intuition that makes memorized formulas make sense.
