A-Level Maths: A1-09 [Disproof by Counter Example Examples]

[liambarnard]

I haven't seen any questions from the new material yet, but are questions worded like in the textbooks? I.e, will we know whether we are being asked to prove by exhaustion, disprove by counter example, or will we just be asked to prove something and work it out on our own accord?

[rosep]

Can I still do past papers from the old specifications ?

If only my teacher could explain like this...

[milesderazones]

For question 1, why is 0.1, 0.01 not the answer

[aaafus]

would 6 work because 1+2+3 is 6 which is not divisible by 4

[shadmanahmed]

You know for the first question, would -1 work.
