Also, is 0 < theta < 90? or 270 < theta < 360? Depending on which of these conditions are specified will determine whether tan(theta/2) is positive or negative.

I'm not sure, the person who originally posted the question did not specify, but yes the domain determines if positive or negative

For the general solutions question (14a), did you guys have two equations, or were you somehow meant to write the answer as one equation?

 

[km1307]

i think it should be (sqroot 2/sqroot 3) faisalabdul16

 

[enigma_1]

Preey sure I got two equations iirc

 

[faisalabdul16]

i think it should be (sqroot 2/sqroot 3) faisalabdul16

Yeah that's what I got except unsimplified form...
Root6/3 =
Root3 x root2 / 3
=root2/root3

 

[Thank_You]

How do you know the answer for the polynomial already?

Oh, got help from a teacher straight after the exam, since we remembered the graph and the intercepts

What were the hardest questions? Did you guys have multiple choice questions?

Obviously they had multiple choice questions... It's the new format for maths papers. 2u, 3u & 4u papers have 10 multiple choice questions

Does anyone happen to have a copy of it that they could send me? Pm me pls

did it today for practice. was a straightforward exam, but the math induction q was retarted. not a good question.

 

[Thank_You]

I liked the induction question haha

The binomial probability in question 9 of multiple choice was so confusing though

All in all, pretty straightforward exam

I guessed the probability, got it right (yay), but I realised after doing it properly was pretty easy, just split up in 3 cases.

I wish I could say the same as you. I can and almost never see circle geometry unless its deadset obvious I couldn't see the mathematical induction and I realised all you had to do was common denominator! *sigh the struggles

Hahahah i did it today as well. Same view on the induction Q it wasn't hard, just weird.

 

[faisalabdul16]

Was not hard at all.

CSSA papers have been harder in the past, this was easy.

Projectile motion question was straightforward.
