Complex Series
Sums of series with C + iS: first taking out half the power (e^(ibθ) − 1 = 2i e^(ibθ/2) sin(bθ/2)), then geometric series of e^(iθ) with half-angle factors, finite sums of cos kθ and sin kθ (and with powers of a), infinite…

Blockbusters with the questions from the Complex Series worksheet: choose its levels for the ordinary hexagons and for the harder ★ ones. Show the answer and the worked solution, or play against the computer with multiple choice.
These are the pages for Sums of series in the A Level Further Maths scheme of work, following Pearson Edexcel A Level Further Mathematics (9FM0). Open this topic in Mr Wells Maths to see it alongside the rest of the course.
