Unless I'm missing something proof by contradiction is in the A level specification (albeit not in AS), contrary to what it says on slide 24. Otherwise thanks for your excellent slides which are invaluable!

I can't find any + & - of fractions in either chapter 1 or chapter 7. They are in the textbook in chapter 1 though I would put them here with other fractions work

I agree with GL. Please see page 11 of the edexcel specification. It says that proof of irrationality of root 2 is needed, students do need to know proof by contradiction. From an MEI course I have been on, I was led to believe they should be about to repeat this for other numbers other than 2 also.

Proof by contradiction including the irrationality of root 2 is mentioned on the edexcel syllabus but you say here it's not on A level, only STEP - have I misunderstood?

You're correct Mr McClean. I've been meaning to reupload my slides with the fix for a while - now reuploaded!
