Check what you remember
Read the wording for your board, then hide it and explain Harmonic form (R cos(θ ± α) or R sin(θ ± α)) in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The equivalent form of a cos θ + b sin θ, where R = √(a² + b²) and α satisfies cos α = a/R, sin α = b/R for R cos(θ - α).
