It would probably be 100... Definitely above 90.

The answers are in this thread - you may need to look back several pages.

Mr.M, if i used degrees instead of radians for the argand diagram questions, will i be marked down?

Do you mean the argument questions?

Probably not on question 4 as it does not give an interval for the angle.

10 gives an interval in radians but you could have converted to degrees and then back again without losing any marks.

yh sorry i was talking about question 4 its just that i always work in degrees i hate radians lol

Edit: tidied up a bit

Mr M.. that last iii) question 10 i think
with w^6 etc , i noticed the answers in i) cubed to make ii)
but i spent the last ten minutes trying to factorise a sixthic or w.e. u call ^6 8)
but yeah how do you work that out?

thankss
