    Perms and Combs

    Order. If they're just looking for the amount of groups you can get, its a combination question - so order doesn't matter however if they're trying to find how much types of ways you can arrange, there then the order matters so its a permutation q.

    Anybody know the order they teach the Adv+Ext 1 Course in?

    Doesn't your school provide a schedule for your courses? Ours gives us a guide on how our topics are ordered. We just did an assessment for Series and Further differentiation for adv and we just did vectors/induction for mx1. We're going to quickly finish trig and then move onto stats for x1 and...

    Need help with roots of unity.

    Not the solution to (v) but just another method for these type of questions; Here's what I did. \sin(A)\sin(B) = \frac{1}{2} \times [\cos(A-B) - \cos(A+B)] \sin\left(\frac{\pi}{5}\right)\sin\left(\frac{2\pi}{5}\right) = \frac{1}{2} \times [\cos\left(\frac{\pi}{5}\right) -...

    yes u should know triangle inequality bc its commonly tested, pre sure u can check past papers and there's at least one or two questions about them. You should know how to prove both ways just in case. also it does help if u know how to derive the other forms if u do plan to use it
