Does anyone know the reason why a june 2013 paper was withdrawn? Was there an error on the paper?

Some papers were lost and could have been leaked for people to see before the exam, you can read about it here : http://www.bbc.co.uk/news/education-22887009

For part b, they say to solve for -pi < theta < pi, but the answers given go above that boundary. Are these answers correct or are they unnecessary? If so, how many marks would you lose for answers above the boundary?

In the article you linked it says "The paper is C3 Unit 6665 mathematics... "

Can anyone telling me what I'm doing wrong in part b? I'm separating the variables but it gives a nasty reciprocal on on of the integrals which proves difficult to solve. Am I going about it the right way? fp2 capture 5.JPG

Seems fine, you get 1 / (2v(1+v)) on one side which you then use partial fractions on to get two logarithmic terms.

seperate variables, gives you 1/(2v + 2v^2) dv = 1/x dx and use partial fractions on the left side

5c)

you just use your answers from part b and plot them on an argand diagram like you normally would.

Q7b, when we solve sin(5theta) = -0.5, the first value we get is -pi/6. Why cant we use that negative value? Can 5theta not be - ve?

No you can use it as long as your range is - 5pi to 5pi and not 0 to 10pi. Your x solutions will still be the same

Have you guys ever come across a question where we had to use the q<= p < 2q condition for drawing a shape?

Cause at the moment I just use my graphing calculator but I'm not sure if I should be learning that stuff anyway
