C4 Is Gonna Be Tough- Differential Eqns Hard!!!

IM FINDING DIFFERENTIAL EQUATIONS REALLY HARD. I HOPE ITS NOT TOO HARD THIS YEAR. ANYBODY ELSE WNAT TO EXPRESS THEIR VIEWS ON THEIR C4 REVISION PLEASE TELL. don't make fun of the caps lock anyway.

Well ive just started c4, only done a few chapters so far. havent really struggled with the differentiation but i havent done it in a while so i must go back and make sure i understand all the "connected rates of change" stuff
binomial expansion is ok, just need to remember to put the right numbers in and get the right expansion

ok calm down-c4 was easy yeah with a teacher. IM self-tutored myself for the whole of AS and now A2 durrrrr.

The differential equations at the last pages of c4, not differentiation which is easy.

What's hard about C4 differential equations :confused:

?

You just need to know how to separate the variables. This means get all the y terms on one side and the x terms on the other and then just integrate both sides. I think C4 differential equations is one of the easiest topics in the module - it's the actual integration which is hard.

Setting up differentials are hard. Solving them is easy :biggrin:

worst bits of c4:
vectors - i had a different teacher just for that chapter, who was rubbish

You make it very hard... :shifty:

Putting terms in y on one side and terms in x on the other - C1
Integration - C2, some C3, some C4

You won't have to do any stupidly complex integration in C4 differential equations... there's nothing really hard in it.

C4 was so easy at the time, I can't even imagine how easy it would be now.

I wouldn't worry about the differential equations - it's only one question on the paper after all. Plus, the questions are designed so that if you can't do the first parts, you can always get marks on the later parts of the question.

That one question can carry up to 10 marks. I've seen a previous paper with a hefty question like that. C4 is relatively straightforward except that if you mess up, alot of marks can go down the drain. :yep:
