The trig questions are here. The functions questions are here. Hope that helps! There is no excerpt because this is a protected post. Hiya. Here are those details about addition formulae that you were after. This first page uses a demo that you’ll need to download. Its free. The areas of the grey squares and rectangles match up giving the identity for sin(A+B) Webpage 1 This second one uses a different proof but it is just as lovely. It comes from the circle [...] Continue reading Addition Rule Trig for Year 13 A-Level Here are the notes from the lesson. year-13-lesson-on-trig-functions-19th-sept-2008 When producing a graph of say, y = cosec x remember that this is the same as y = 1/(sin x). Use what you know about sin x to help you produce the graph of y = cosec x. Hope you like the graphs! MW
Here’s the link to the original post from the lesson on Transforming Trig Functions. A powerpoint on transforming general functions and curve-sketching (taken from C1 AS work, but still relevant) is here; another one to look through for revision is this one on functions and graphs too. Here’s the link to the slides from today’s lesson going over the Trig exam questions. And the experiment typography piece I mentioned is can be seen here. There’s a neat time-lapse video piece of it here and a brief outline of how it was done here too. Unfortunately, it’s in California (like we get enough sun here [...] Continue reading Mr Brewin’s Y11 – Solution to Trig Questions It would be great if Talia and Marnie could have a read through of the slides on this before the next lesson. We’ll have another run through of the theory quickly then, and do some examples. Next lesson: Tuesday after school. See you then! The slides from C2 Chapter 8 are here. Trouble-shoot questions from Chapter 8, plus some exam qus tomorrow… we’re getting there! Click here to see the notes from our lesson. Homework is from Exercise 8G on page 125, question 1, 2, 3, 5 and 6. |
