oK I have a question about the formulas that need to learnt for Maths... Eexcel AS
the syllabus only states a few e.g in stats- probability for independant events but doesnt mention for mutually exclusive events and the other 4 probability formulas in the heinemann book... do these still need to be learnt?
and it says standards deviation = root of variance... do we need to learn the variance formula as well?
There are a lot of formulas not mentioned... i think perhaps these are provided in the formula booklet and that's why the are not mentioned...?
i just don't want to end up not learning some important formulas

If you know the standard deviation formula then you know the formula for variance...

I'm still doing GCSE's but I'd expect it's better to know the formulas anyway, but probably you'll have to know the ones for stats, and the mutally exclusive events etc isn't difficult

We've been told to learn all the formulae that they've (tried) to teach us and not rely too much on the formula book... still a lot of stuff to learn tho...

Just learn all your formulas, it can only be good for you. And plus you might save some time by using something from memory than flicking through a formula booklet.
If you do enough questions you will remember them without needing to specifically memorise them.

The formula book is useless for P1; it is invaluable for the later modules though.
