Sorry to nudge an oldish thread but if either of you have these and didn't mind sending me a link or something it would make my own sixth form interventions much more streamlined!

I always go for "write it as a geometric sum so you can use the sum formula" then look at the question to see whether it's the real or imaginary parts we need. Then part b is usually a multiply by the conjugate...

Thanks! Do you know if there's anything about the impact of two teachers (one stats one mechanics) Vs one covering everything in one year?

Can anyone suggest any reading (blogs, posts, research etc) on "being a good maths key stage 5 lead"? Any guidance/best practice/communities/things to have in place would be greatly appreciated! #UKMathsChat #MathsToday
