This is an 11 slide PowerPoint that covers BTec National Engineering (A-Level equivalent) on the topic of Trigonometry and Triangles. It covers the use of the trigonometric functions applied to right-angled triangles, Pythagoras’ theorem, and the Sine and Cosine rules applied to any triangle. There is a worksheet and answers to the worksheet are included. This is the ninth PowerPoint in this section (Mathematical methods).

This is a 13 slide PowerPoint that covers the topics of Vectors and Phasors. It covers an introduction to vectors, resolving vectors into components (using trigonometry), finding the sum of vectors in 2 dimensions (using trigonometry and Pythagoras’ theorem), introduction to phasors and the sinusoidal formula including phase-difference. A knowledge of trigonometry (see previous lessons in this series) is needed.
