FP1 Edexcel Practice Paper A Q7
Hi there,
Further Maths FP1 help needed! I am a gap year student self teaching the full further maths A2.
I can't see why the mark scheme produces the answer it does:
7. Given that z=1+(root3)i and that (w/z)=2+2i find
a) w in the form a +ib
b) the argument of w
The mark scheme gives the answer
7pie/12 but I keep producing the answer -5pie/12
Any help would be greatly appreciated!
Thanks!
