Hmm, I'm resitting this exam. I need 80 UMS for the A*, so I'll probably just look over vectors in June. Hopefully the paper will be easier than that pile of **** we got given in January.
Hey I'm doing this exam in June too!
Any chance of getting the January 2013 paper?

Hi, I have a paper copy of the Jan 13 C4 paper. I will write up the questions on here Tommorow if a Mod approves of me doing so.

Rsin(x+a) is the same as Rsinxcosa + Rcosxsina right?
So make that equal 2sinx + 5cosx
you the the sinx cancel on one side and cosx on the other,
leaving you with Rcosa = 2, and Rsina = 5
Square both the equations then add them,
giving R^2(cos^2a) + R^2(sin^2a)= 4 + 25
Take R^2 factor out >> R^2(cos^2a + sin^2a) = 29
sin^2 + cos^2 = 1 right?
so R^2 = 29
R is the maximum value because you've stretched the curve in the y direction by R
so the maximum value is root29

" find the general solution of the differential equation:
sec^2y/cos^2(2x) x dy/dx = 2"
Anyone help please? thanks!

Is that meant to be sec^2(y) or sec(2y)?
Does anyone have the Jan13 paper? If someone could email it me that'd be great :smile:

It's never hard, they always have separable variables, so it's just integrating.
