2026 Year 11 Extension 1 Mathematics (Sinclair)

Tue 12 May

  • Comment: We did mixed questions in class today, touching on composite functions, absolute values, inverse variation.
  • Work on Classroom: I added a PDF called Solving Trig equations that is likely to be of use. It explicitly covers lots of question types and contains the theory of how to solve them.

Mon 11 May

  • Set 8: 2026-05-11-Set-8-trig-and-revision.pdf
  • Textbook work: 6.06 (composite functions)
  • Comment: Advanced NOA given out today. A helpful list of exercises is shared on chat. Set 8 above is an assignment to be handed in on Wednesday.

Tue 5 May

  • Textbook work: As already specified: 5.03, 11.04, 11.04. However, I have posted alternative work in Classroom. Look in the Trigonometry (Adv) topic. These exercises better fit the way we have approached the topic, and don't include any radians.
  • Comment: We are in the middle of some working lessons, and will soon tackle old friends like sine rule and bearings and ... We have learned the new Year 11 theoretical content first, to give you a longer stretch of time in which you can get used to it.

Tue 31 Mar

  • Comment: We have started a new topic called Further work with functions. It doesn't correspond neatly to a textbook chapter. Here are the skills we will learn:
    • Inequalities (2.05, 2.12)
    • Graphical relationships (6.07–6.09)
    • Inverse functions (7.08–7.10)
    • (You should also be comfortable already with 4.13)
  • Comment: We did all of Inequalities while people were absent on Art camp (and the barista course). The questions we did are on Classroom under Further work with functions. I'll help people catch up on Thursday 2 April.
  • Textbook work: 2.05, 2.12, 4.13 (lower priority)

Tue 10 Mar

  • Textbook work: Cambridge 10F (roots and coefficients) given out in class. Questions and answers are on Classroom. Maths In Focus 7.07 deals with this as well.
  • Comment: We've almost entirely finished Polynomials now and will spend our remaining lessons focused mostly on things that will help you in your assessment tasks.

Fri 6 Mar

  • 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).

Mon 2 Mar

  • 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.

Fri 27 Feb

  • 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.

Tue 17 Feb

  • 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.

Fri 13 Feb

  • 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.

Thu 12 Feb

  • 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.

Mon 9 Feb

Tue 3 Feb

  • 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.

Mon 2 Feb

  • 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.

Fri 30 Jan

  • 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.
