Web25 jan. 2024 · Sin Cos Formulas: Trigonometric identities are essential for students to comprehend because it is a crucial part of the syllabus as well.The sides of a right-angled triangle serve as the foundation for sin and cos formulae. Along with the tan function, the fundamental trigonometric functions in trigonometry are sin and cos. WebSolution: To convert sin x + cos x into sine expression we will be making use of trigonometric identities. Using pythagorean identity, sin 2 x + cos 2 x = 1 So, cos 2 x = 1 - sin 2 x By taking square root on both the sides, cosx + sinx = sinx ± √1 - sin 2 x Using complement or cofunction identity, cosx = sin (π/2 - x)
