Build the intuition first, practise actively, and reveal worked answers only after making your own attempt.
- 1Review the conceptsStart with the definitions, diagrams, and core formulas.
- 2Work through the interactive slidesUse the optional hints to unpack formulas, diagrams, and common traps.
- 3Solve before checkingAttempt each problem, then compare your reasoning with the worked solution.
