I definitely found it harder than other papers and LONGER. I normally finish in 1.5 hrs however this exam took the full 3.

If its increasing the gradient is positive f'(x) > 0 If its decreasing the gradient is negative. f'(x) < 0 If the function is at a decreasing rate the function is concave down (i.e. f"(x) < 0) If the function is at an increasing rate the function is concave up (i.e. f"(x) > 0 )

Anyone have any good tips for probability? It is my most despised topic in the entire syllabus, I just lack the common sense for it. Any tips would be greatly appreciated. Thanks :)

I go to malek fahd and they have the same policy in place, so idk :/

Hi all For sketching the f'(x) to f(x) graphs, how would I justify certain things? For example in a 2007 Ruse trial Q9 it states that point C is a local maximum on f'(x) and then goes on to ask what type of point occurs at C on y = f(x). It then asks for a justification. PS i have no clue what...

Oh man, I feel ridiculously silly right now. Thanks very much. :)

Thanks mate, much appreciated :) What about cos theta? How would you go about Q2?
