In this part 2, the last 5 questions in SSC CGL Tier II Solution set 7 on trigonometry 1 of suresolv.com are solved with clear explanation. Approach has been to solve each problem in minimum time using basic trigonometric and algebraic concepts and suitable methods. You should also be able to understand and apply the methods on your own.
A few of these 5 problems may seem to be difficult but nevertheless are solved in quick time using trigonometric and algebraic concepts and techniques.
Pattern discovery and suitable use of concepts and method have by far been the main components of the quick solutions. The notable of the methods used are, friendly trigonometric function pair, strategy of target simplification first, componendo dividendo, basic trigonometric relations, abstraction, trigonometric functions as variables, solving linear equations, compound angle trigonometric relations, end state analysis approach, trigonometric function conversion, supplementary angle trigonometric functions, trigonometric ratio values, algebraic techniques, and mathematical reasoning.
