Q10 ii) I've made the Argand diagram and did the shading. How to do the last part.. "Find the greatest value of arg z for points in this region."
Thanks

Can someone help me in question 6 of this paper: http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_w12_qp_62.pdf

I don't understand these type of questions. How do we tell if two events are independent from each other?

It is stated in the question that the die is "fair" which means that each event has an equal chance of occurring. If the die would have been "biased" then some events would have a greater chance of occurring from others. But it still wouldn't affect the outcome of the other events. Meaning the events are independent.

The events being independent means that one outcome doesn't affect the next outcome.

mod = root of ( x^2 + y^2) =1
(x^2 + y^2 )= 1^2
(x^2 + y^2 )= 1----------- i

then the argument
tan theta = y/x
tan (2/3 pi)= y/x
- root 3 =y/x
y= -x (root3)----------- ii

Please help with shading the Argand diagram

The argand diagram will be a circle of the radius 2, and a diagonal line with a negative gradient. You shade the part enclosed below the line, within the circumference of the circle.
