Trigonometric Proofs - Part 2 - using Sine and Cosine rules

This lecture builds on Part 1, in which 'trignometric proofs' using basic trigonometry and pythagoras' theorem were undertaken. This Part 2 lecture again relates to solving trigonomentric proofs but this time using the Sine and/or the Cosine rule. A worked example and two questions are included to try and illustrate the prcess involved. Simultaneous equations will need to be generated and solved to prove the formulae as stated in the respective problems.
