- Comment: Yesterday and today, we have learned about graphical inequalities in general, quadratic inequalities in particular, and sketching polynomials based on their factored form. We know about intercepts, bounces and kinks.
- Textbook work: See Classroom for "Cambridge 10B" (on graphing polynomials). We will do this instead of MiF 7.05–6.
- Textbook work: 4.09 for quadratic inequalities
- Further comment: We still have not learned "equivalent polynomials" (Example 9 in the textbook), so you can't do 7.03 Q15. Some other questions in 7.03 are likely to be intimidating as well; we'll get to them. Apart from that, I'd hope that all of 7.01–7.04 are accessible to you now. Next week we will consolidate our knowledge of polynomials and get ready to attack the final exercise (7.07 – sums and products of zeroes).
- Comment: We started Polynomials today. It is an Extension subject and is included in your first Extension task (NOA given today). We have not finished everything in the Advanced topic (Functions), but we've finished all we need for the task. We will return to that topic after your tasks. The other classes are doing this as well.
- Textbook work: 7.01 all questions except 11–14. (I'd rather we practise sketching in class before you do it at home.) It would be good to complete this ASAP so we can deal with any difficulties.
- Set 6: 2026-02-27-Set-6-functions.pdf
- Textbook work: I wrote the relevant exercises on the board yesterday (it was in our heading). Try to do some questions from each of these.
- Comment: We did a range of equation and inequality questions.
- Textbook work: 2.01–2.05, with more focus on absolute value questions than other questions.
- Set 5: 2026-02-13-Set-5-mixed.pdf
- Textbook work: 4.01–4.03, as already mentioned.
- Comment: We will do answers to Set 4 and Set 5 on Monday.
- Comment: We covered a lot of functions knowledge today, and will cover just a little more tomorrow. Then you will have time for textbook work (see below), which you can start now if you wish. I will check Set 4 tomorrow morning.
- Textbook work: 4.01–4.03, with the usual advice that you skip questions that are too repetitive. Please let me know of anything you don't understand.
- Set 4: 2026-02-09-Set-4-mixed.pdf
- Extra work: See Cambridge exercise on Classroom
- Set 3: 2026-02-03-Set-3-mixed.pdf
- Textbook work: Harder questions in 3.02–3.04.
- Comment: We've mostly finished Permutations and Combinations. Now it's just practice. We're not doing 3.05–3.07 in this topic.
- Comment: We did the handout "Permutations, combinations and counting questions" today. Answers are on Classroom.
- Textbook work: None today. We have a bit more to learn before digging further into 3.02–3.04.
- Set 2: 2026-01-30-Set-2-mixed.pdf
- Textbook work: Just easy questions for now. We'll get into the harder ones in Week 2. Do Exercises 3.02, 3.03, 3.04: just Q1–10 for each exercise. Feel free to skip some when it feels totally repetitive.
