Good luck to everyone sitting the 2019 exam. This thread will probably become active in the lead up to prelims and the final exam. Use this thread to ask any questions or problems that you have and I'm sure someone (me or others) will gladly give you a helping hand.


EDIT- UNOFFICIAL MARKING SCHEME

The calculus can be very tricky sometimes. Is there anything that is maybe troubling you?

Not anything in particular, it's just a hard topic to get around.

Can I get a little help with this question? it's a binomial theorem one

(n )
(n-2) =45, solve for n. it is a positive integer.

The brackets are all just one big bracket, I'm bad at formatting.

I always get to n^2-n+90=0 but can't get any further because all my answers will be complex numbers. Thanks for reading.

The equation is meant to be n^2-n-90=0!
Missed a negative...so I got that n=10

If anyone's struggling with calculus I recommend watching 3Blue1Brown's Essence of Calculus series on youtube, there's a lot of great visualisations of the meaning of the derivative, integral etc

Question 5...
I have got the first quadratic root and it is z^2-10z+26, assuming it is correct, how do I get the last root? And how do I plot an Argand diagram?

I got 67% in my prelim which is okay. Just fire through past paper questions and learn the marking schemes and make summary notes and answer questions using your own personalised notes.
