You do.

Thanks.

Yes.

I think you do.

Consider x > -3 and x < -3 The former gets you the same inequality in (a)
Are you sitting the exam?

Are you sitting the exam?

The IAL version, yep.
4. Why is tan(arg(z+3))=1/2 not a half line?

Fp2 06 8b
5. Had a quick question, in FP2 June 2015, how do you know the answer to 1b? The answer is apparently x>1 however I dont understand how we're just meant to see that since it is a 1 mark question.

What two values can the argument take?
7. Can we be asked to form a differential equation based on a model just like C4?

Not sure what you mean.

Arctan(0.5) would be one value?
9. can anyone help me out with JUNE 2013 (R) question 6 maybe draw it up for me because im so bad at de moivres plz ty
10. Im a little stuck here guys. How do we answer transformation questions that involve arg (z-z1)= angle

Think about what tan looks like.

I wonder if we'll get all the points for writing down the solution for a relatively simple partial fraction.
well our teacher told us if you use the "cover up" rule, then you need to state it so they don't suspect anything.
13. Is the TI-83 plus calculator permitted for this exam or not?
Doesn't matter too much if it isn't - I'm just slightly concerned about plotting polar graphs at the moment.
14. pi+arctan(0.5)

Ok so these are two possible values.

Do I essentially draw two half lines?

16. Is it me or are the IAL past papers easier?

i'm pretty sure you can use it, it doesn't have algebraic integration/differentiation does it?

I think just numerical

Essentially yes, but if you think about it adding pi rotates it to the other side, so youre drawing two half lines that start from the same point and go in opposite directions, aka a full line

Wasn't sure which part you were stuck on so I wrote up a full solution, hope it helps
