1. Hey, been covering all of my topics for FP1 tomorrow and I'm pretty solid on the topics but this one questions has completely thrown me off. If someone could explain to me how I'd go about doing it, step by step, that'd be great, thanks
(for clarification it's question 4)

2. Eat on it!

Multiply the fraction by the complex conjugate of the denominator.
4. Think this is correct

You shouldn't really post full solutions on here, but if the OP's exam is tomorrow I'll let you off!

Note that you can save a bit of time in the working - if z = x + iy has an argument whose tangent is 1 then the real and imaginary parts of z must be equal.

So once you've worked out the complex number in terms of fractions with real denominators you can just write down 5p = 6 - p^2 and solve from there

Haha, don't really post on here so wouldn't know, but thanks for the heads up!

That's a good point actually, I don't know why I didn't just do that but then again i'm so very used to giving so much working out because otherwise I make careless mistakes :P Thanks!
