In chapter 10- Sine and Cosine Formulae and Their Applications, questions that are based on some trigonometric relations with elements of a triangle are covered. Experts state that if you study these solutions you can get good marks in the exam. You should refer to these solutions when you have tried to solve the questions by yourself. These solutions mainly concentrate to deliver learning various Mathematical short tricks for quick and easy calculations.
