<p>A 12-episode visual video series by Grant Sanderson of 3Blue1Brown that builds intuition for calculus from first principles — derivatives, integrals, limits, the chain rule, and the fundamental theorem of calculus. The aim is for viewers to feel they could have discovered the ideas themselves rather than memorise them.</p><ul><li>Free to watch on YouTube and 3blue1brown.com</li><li>Chapters include the paradox of the derivative, power rule through geometry, chain and product rules, Euler's number, implicit differentiation, limits and the ε-δ definition, the fundamental theorem, higher-order derivatives, and Taylor series</li><li>Self-paced; around 5–8 hours of total runtime</li><li>A strong companion to H2 Math calculus content for JC and upper secondary students building mathematical maturity</li><li>Text versions of each lesson are published on the 3Blue1Brown website alongside the videos</li></ul>
