In this PowerPoint, we begin by introducing the new set of formulae involving the 3 “new” trigonometric functions: secant, cosecant and cotangent. We explore the formulas for the addition/subtraction of two angles as well as formulas for the “double angle”. Additionally, we also study how to express certain algebraic expressions containing trigonometric functions in a way which facilitates important calculations related.
Afterwards, we investigate the process of differentiating and integrating trigonometric functions, by exploring different scenarios and appropriate algebraic techniques. For each case, there are worked examples, guided steps and clear explanations.
In the last section, we explore different examples of worked exam-style questions, where all steps are clear and detailed.
Hopefully, this resource can help students in their preparation for examinations and can also be used as a complementary teaching tool, when delivering these topics.
