 10/7/2018 We warm up for the new academic year by solving problems from some recent mathematical competitions.Handouts: Lesson Handout [Show less] 10/14/2018 We start our exploration of quadratic equations with Vieta's Theorem. As usual, we also do some geometry.Handouts: Lesson Handout | Homework [Show less] 10/21/2018 We solve some problems on the properties of general functions, and learn to apply Vieta's theorem from last week. As usual, some geometry.Handouts: Lesson Handout | Homework [Show less] 10/28/2018 We continue exploring quadratic equations by completing the square and learning the formula for the roots. We also start working towards quadratic inequalities, in particular seeing when a quadratic function is positive or negative.Handouts: Lesson Handout | Homework [Show less] 11/4/2018 We take a step back from learning fundamental facts about quadratic equations, and practive what we have already learnt on some problems. Geometry also makes an appearance.Handouts: Lesson Handout | Homework [Show less] 11/11/2018 We introduce parabolas -- graphs of a quadratic equations, and solve some problems regarding them.Handouts: Lesson Handout | Homework [Show less] 11/18/2018 We use the theoretical properties of quadratic equations established during the last few weeks to solve some concrete problems. Also: more geometry. [Show less] 12/2/2018 We see what we have learned about geometry and quadratic equations with an individual problem-solving session.Handouts: Handout [Show less] 12/9/2018 Fun and games! [Show less] 1/13/2019 We start a few new topics for the quarter -- weighings, logic and ruler & compass constructions.Handouts: Lesson Handout | Homework [Show less] 1/20/2019 We continue with the topics of weighings, logic and straightedge & compass constructions.Handouts: Lesson Handout | Homework [Show less] 1/27/2019 More straightedge and compass constructions, along with harder weighings and logic problems.Handouts: Lesson Handout | Homework [Show less] 2/3/2019 We focus more on using invariants in combinatorial problems about processes, and also continue with straightedge & compass constructions.Handouts: Lesson Handout | Homework [Show less] 2/10/2019 We continus with our topics of invariants and straightedge & compass constructions.Handouts: Lesson Handout | Homework [Show less] 2/24/2019 We continue with invariants, semi-invariants and geometric constructions.Handouts: Lesson Handout | Homework [Show less] 3/3/2019 We continue our route to triangle siilarity by learning the intercept theorem.Handouts: Lesson Handout | Homework | Reading [Show less] 3/10/2019 Our multi-week journey towards similar triangles culminates with the proof of the two main theorems about them.Handouts: Lesson Handout | Homework [Show less] 4/7/2019 We start a new topic of combinations and Pascal's triangle. Also a problem on triangle similarity.Handouts: Lesson Handout | Homework [Show less] 4/14/2019 We continue studying combinations, introducing the binomial formula and Pascal's triangle. [Show less]
