Lectures

Alongside the PoTDs, CNCM also has lectures on specific math topics. These are made on the same topics that the PoTDs during that week will cover and aim to help members learn important competitive math concepts and get good practice with them.

Lecture 1: Roots of Unity Lecture 2: Complex Numbers in Geometry Lecture 3: Recursion, Ball and Urn Method Lecture 4: Euclidean Algorithm, Euler's Totient, Orders Lecture 5: Lifting the Exponent Lecture 6: Combinatorial Identities Lecture 7: Trigonometry in Geometry Lecture 8: Finite Differences Lecture 9: Power of a Point and Cyclic Quadrilaterals Lecture 10: Logarithms Lecture 11: Incenter-Excenter Lemma Lecture 12: Mass Points and Barycentric Coordiantes

We are currently updating CNCM's lectures, there are quite a bit more than the ones listed. To see an up-to-date list of our lectures, join our Discord server, which can be found in the "Join Us!" page.
