Delayed retrieval and prerequisite connections

Delayed retrieval: trigonometry and prerequisite connections

Return to this set after intervening study rather than immediately after the Module 9 practice. It checks whether you can retrieve trigonometric ideas while also using earlier algebra, circular geometry, units, function domains and average rates of change. The question order deliberately mixes methods without naming the topic needed for each solution.

Half the bank focuses on Module 9 reasoning, and half emphasizes its prerequisite connections. Single-select and multiselect items include inverse-function inputs, reciprocal-function behaviour, phase mismatch, signed ratio reasoning and restrictions that survive algebraic simplification. Explanations support review after an independent attempt; they are not a substitute for writing down a method first.

How to use the evidence

Record whether an error came from forgotten knowledge, an incorrect model, a missing domain restriction or an algebraic calculation. Revisit only the relevant topic and then check the skill with fresh work. These selected-response tasks provide provisional evidence of retention, not proof of independent written or graphical production. The set does not schedule reminders or claim that one successful attempt establishes lasting mastery.
