I just did that paper it was difficult I have to say, everything except the alpha and beta bits are part of the same spec.

How you state it using set theory is

\forall n, n \in \mathbb{Z}^+

.

This reads as "for all n where n is an element of

\mathbb{Z}^+

".

Thanks - so I should say 'all n and nEZ+' ?

How do you factorise three term quadratics with three variables. I had to find the intercept of a normal at a point with a hyperbola, I got the 3TQ right, but I couldn't factorise it by sight, it was:

P^3x^2 + c(1-p^4)x -c^2p =0

For part (b)

C(-2a,\frac{-2ar}{q-a})

, so why do you have to use

\frac{2ar}{q-a}

as the vertical distance of OCS? How would you know if

\frac{-2ar}{q-a}

is positive or negative?

I assume you treat it like a quadractic in the form: ax^(2) + bx + C, then either factorise as a quadractic or use the formul

Yeah I did that paper as well- you can work it out with the info given in the question i.e. a is a positive constant etc... can't be rmb the exact wording
