This is the part 1 of the solutions of first 5 questions in * SSC CGL Tier II Solution set 11 on trigonometry 2*. All 5 problems including the tricky ones are solved quickly in a few steps using suitable 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, trigonometric function factoring, basic trigonometric relations, trigonometric functions as variables, variable elimination by substitution, trigonometric ratio values, strategy of target simplification first, algebraic techniques, and mathematical reasoning.
