Chain rule is alright I'll admit, everything else, nah. I don't like algebra really.

Trig isn't actually any harder than C2, its just the introduction to the unnecessary functions. Apparently they're major in C4

I disagree

But like how are the inverse trig functions actually useful? Just makes everything longer
Mathmo is someone doing maths at Cambridge

Inverse trig? Like arctan(x)? Or 1/tan(x)?

I thought you were

Cot(x). Wtf is arctan?

Nope! never ever ever!

Arctan is basically...

tan(x) = 4
x = arctan(4)

So you've used them before, just written it as tan^-1 etc

Lol because chemistry is way better!!!

For a second I thought you did some weird logging

I always say "tan to the minus 1"

It is I'm only doing Ionic Equations now but I'm loving it

see it is confusing because if you think "tan(x) to the minus 1" it'd be "1/tan(x)" but that's cot!

Ahh, back when chemistry was that simple

Nah, I mean like "tan to the minus 1 of x" just like I'd say "f to the minus 1 of x" for inverse functions
7. Does A level Geography have any scientific elements in it at all? It's accepted as a science for so many biology courses Many also accept ICT as a science, which annoys the hell out of me!

I can't wait for it to get hard! Although yesterday, balancing Aluminium Hydroxide + Sulphuric Acid was so irritating

Geography is quite scientific, like plate tectonics lets say... They identify things with gravity anomalies, thermal hot spots etc

I found unit 1 harder than unit 2 tbh

2Al(OH)3 + 3H2SO4 -> Al2(SO4)3 + 6H2O

10. 1400 page biochemistry book arrived today

Yeah, that's right but it took me forever...

It's actually really grown on me, I didn't like it when I did it in year 10, but I've learnt to appreciate it this year

Deal, I think I'll do Wuthering Heights considering there's a lot to get through
