Learners over-generalise a special case of introducing cosine graph to every situation.

Correction — Present a deliberate non-example and ask why the rule fails.

Students treat introducing cosine graph as a rule to memorise rather than a relationship to understand.

Correction — Anchor the rule in a visual model first, then abstract it — the model is the explanation.
