Start viewing this video. Once the table of data is drawn (at 00:30) copy the table into your orange book.
Attempt to draw the cumulative frequency curve and use it to find estimates of Lower Quartile, Median, Upper Quartile – view the video first if you wish.
Then (this part is not included in the video) draw a box and whisker plot under the cumulative frequency graph.

Use the x-axis as the number line above the box and whisker plot.

If you need help drawing a box and whisker for the data, see this video

A nice example of a worked GCSE question. Not the hardest type of question (the proofs are the hardest) – I will find a good example of these and post that.

Using CAST in radians

Here’s the powerpoint we used in class including answers to the whiteboard questions

Simple Trig Equations

If you need to check some practice questions you can use the Wolfram Alpha website. It will interpret your query as being in radians so you can try typing in something like:

solve cos x = (sqrt 3) / 2 for -pi <= x <= pi (click here to see result)

Trig Graphs

Here is a different way of showing how the trig graphs are derived.

Look at the changing ratio of the two sides as you drag the right end of the pink horizontal line upwards.
