Here’s a presentation which may help you work our what happens to various co-ordinate points when you transform graphs in different ways.
Hope it helps!

Here is another puzzle for those that have finished the first one. Enjoy. Puzzle 2 Mr W
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. 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 for the material we covered yesterday and today. Here’s the Powerpoint of the lesson on Coordinate Geometry (Chapter 5) from today. Work for next Weds: Ex 5A, 5B, 5C. Marnie – please download these slides and have a look through. Should be fairly self-explanatory |
