Okay! How do we find the normal of OAB?
yu got OA and OB ryt..?
just find the cross product of OA and OB to get its normal

when you cross two vectors you get a vector that is perpendicular to both of them...Since OA and OB lie on the same plane their cross will give the vector that is perpendicular to the plane ....Okay! How do we find the normal of OAB?
Thank you so much! I got it now!yu got OA and OB ryt..?

gr8. ...Thank you so much! I got it now!
nah...no time waste.. i like solving maths problems.. just tell me if yu got it 100% or not.. ?
like i would say no ..So I can call on you for help if I'm stuck in any question?
can someone tell me how to find the least/greatest value of arg z or mod z. I have no idea about what these are.
Hi, I want to ask about question 8 (full one, including part ii) in this paper.
How would I go about that? I realize I have to perform a double angle formula in part (i), but I just can't seem to get it right. Any help would be much appreciated!
It was too tedious to type all the workings , so here is the one that I solved
And umm.. sorry, it's too light. You might have to zoom in a little.

Question 9(ii)
and Question 10.
Anyone?

Thank you! I actually think I will stop solving for now because what I thought I never knew how to solve was a VERY silly identity mistake from my side that messed up the whole question.
Again, thanks a lot!
P.S. You have a great handwriting...
Sure Im waitingI've totally reached my saturation point right now, I'll help you tomorrow first thing in the morning. Sorry

Q10 ii) b) Why do we have to take the square root of z that we've found in a) ? Since they're asking for z^2, shouldn't we square the values of z that we got in the previous bit ?
MustafaMotani ?
Or anyone else ?
