Fish, I know you're here somewhere. HL Maths has already ruined me.

Even the year 13 Further Maths people couldn't really help me with my homework.

Here's a question from it:

z^2=9i

Express this in the form x+iy or something... good luck.

IM SO CONFUSED/TIRED/WTF
z =

I get:

(not sure if it can be simplified, but I haven't tried to )

You're basically trying to find the square root of 9i.There are many ways to do this but this is what I do:

(x + iy)^2 = 9i

Expand the LHS and equate the real and non-real terms.

Maths, Further Maths, English Lit, French, History. All great subjects, but also all quite heavy on the workload front.

What did you take? How are you finding the workload?
You're the only person I've met to have my subjects!

(I'm not doing History though)

I've chosen young enterprise Would it be advisable to chose one that relates directly to the career you would like to pursue? Because I'm not sure whether I've chosen the right thing

But not essential
