Squeeze reasoning and basic trigonometric limits

Develop squeeze reasoning and basic trigonometric limits using radians, inequalities and algebraic identities. Compare a numerical conjecture with a proof outline and avoid using derivative formulas to justify the foundational sine limit.

Build from interpretation to calculation, transfer and error diagnosis. Work out each answer before viewing the choices; single-select and select-all questions include worked explanations for checking assumptions and reasoning.
