Ah thanks :_)

I quite agree especially as long division is very rarely taught in secondary school anymore.


Arsey,

I should make a petition :wink: :biggrin: :cool:.

Getting back to business, this is regarding C4, if a question has a trigonometric function normally you have limits, let it be degree or radians, you will know what mode to put your calculator in.

C4 June 2007 Question 8, is about differential equation parts a and b are fairly easy the same can be said for part c and d, but part c and d are regarding a trigonometric function there are no limits given. The only way you can achieve the answer is by using radians mode, hence implying that degree mode will obviously not work.

Question http://prntscr.com/3mm15i

What i have been taught is, if the question is about trigonometric function, always use radians unless otherwise told to use degrees, can you vouch for that?
If only Arsey has a donate button :rolleyes:

you can only use radians when differentiating or integrating trigonometric functions.

Hey, I seem to have come across a C4 paper from June 2013 with no mark scheme available anywhere, I anyone has it can i see it if not anyone fancy making one??? :smile:

Arsey,

Cool, thanks for that.

A D1 revision thread would be nice please.

Thanks Arsey.

Your S13 C4 W paper links to the June 2012 C4 paper though.

I'm assuming it's supposed to be the original paper?
