Hi guys How do you do a log question if the bases are different and you have to find x, for example Log (base x) 5 - Log (base y) 3 thanks
It won't happen, promise. It's impossible (I'm a maths teacher)

The last thing you want to do before any exam is an all nighter! You will be cramming information into your brain that it won't even retain when you get into the exam hall.

The best thing you can do for yourself is get a good night's sleep. Stay up till 1 max and get to sleep if you really want to do yourself service for the C2 paper.

But that's just my 2 cents... (or pennies, in this case )
its what i find helpful and i stress a lot so i will have a sleepless night regardless, so i might as well be productive haha
11. Make sure you revise Fermat's Last Theorem, that is very likely to come up in tomorrows exam

No... looking forward to this paper though. 99% guarantee it will be a b****.

You'll confuse some people! Don't do that.

One of the C3 identities is cosx/sinx = cotx
