Check what you remember
Read the wording for your board, then hide it and explain composite trigonometric arguments in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: WJEC
When squaring composite arguments, cos(kθ) becomes 1 − (kθ)²/2 = 1 − ½k²θ², ensuring the factor k is squared inside the bracket.
