The learner is formally introduced to definite integration, followed by a worked example. The application of definite integration to area between a curve and coordinate axes is briefly explained. Learning of definite integration is enabled by a process of worked examples followed by interactive ‘multi-choice’ examples (with worked solutions). The learner consolidates prior learning on integration, indices and surds to attempt more challenging exam-style questions. Learning is consolidated by worked examples followed by interactive self-assessment questions (with worked solutions if needed).
