How this rating is calculated
We count the exam years containing this skill heading in the same subject and qualification, across the latest five available sittings (2022–2026). Several matching questions in one year still count as one year. This is a question-type match, not a claim that identical wording repeats.

Automatic topic matching is provisional and can miss or misclassify questions. A question with several skills uses its first indexed skill for this meter. A question without a classification is not rated. A source gap is unknown, not a zero. Mythic means no indexed match in a complete five-year source window; it does not mean impossible. This is historical evidence, not an exam prediction or a reason to skip a topic. Index checked 2026-10-23.

Method guide · plan your approach
Original ScotSpark strategy guidance, not an official model answer or a question-specific worked solution. Skill matching is provisional; use only the advice relevant to the actual question.
- Identify what is being asked and choose the relevant relationship or algebraic strategy before substituting values.
- Set out each transformation or calculation. Keep exact values and intermediate precision until the final answer.
- Check the domain, units, rounding and whether every solution in the stated interval has been included.
Trigonometric equations
Find every solution in the specified interval.
Domains, ranges and transformations
Track how inputs, outputs and key coordinates change.
Wave-function form
Combine sine and cosine terms into a single wave expression.
Trigonometric graphs
Identify amplitude, period and transformations before sketching.
