i missed my first further maths lesson and he has set some hwk but i am really confused....i would really appreciate some help. the question is:
Find the values of p and q given that p+qi=1/12-5i

You could also think about it as rationalising the denoninator.

No, You are 'making' the denominator real not rationalising.

Admittedly it's never a good idea to use wrong terminology, but you get where I'm coming from.

I said it could be thought of as rationalising as the processes are fairly similar. I never said it was rationalising.

Multiply the 1/(12-5i) by (12+5i)/(12+5i)
This gives (12+5i)/(144+25) = 12/169 + 5/169 i
so p=12/169 , q=5/169
This gives (12+5i)/(144+25) = 12/169 + 5/169 i
so p=12/169 , q=5/169
