WebA-Level Edexcel C3 January 2010 Q3 (a) Worked solution to this question on trigonometry. (a) Express 5 cos x – 3 sin x in the form R cos (x + α), where R > 0 and 0 < α < π/2. A-Level … WebEquations involving trigonometric functions of a variable are known as Trigonometric Equations. Example: cos 2 x + 5 cos x – 7 = 0 , sin 5x + 3 sin 2 x = 6 , etc. The solutions of these equations for a trigonometric function in variable x, where x lies in between 0 ≤ x ≤ 2π is called the principal solution.
