This is a whole lesson on trigonometric identities. This builds on the previous lesson on trig equations to add in the extra teaching and detail needed at AS Level mathematics.
This lesson has a starter, learning objectives, loads of excellent teaching slides, examples and plenary. It also comes with exam questions that I normally use, so that pupils start to become familiar with exam style questions. It also comes with the answers (detailed mark scheme) and a handout of mark scheme jargon. This is an opportunity for pupils to become familiar with mark schemes and how to interpret them, which will help them to maximize their marks in exams. 16 slides.
This lesson does come as a wider series/ bundle on trigonometry and is available as such at a discounted average price. I highly recommend it as a series as each lesson does naturally build on the lesson before and does form an excellent sequence of lessons.
