cot A = 1/tan A = 1/(1/√3) = √3 — (1) Using Trigonometric Identity: 1 + tan²A = sec²A 1 + (1/√3)² = sec²A sec²A = 1 + 1/3 = 4/3 sec A = +√(4/3) = +2/√3 or sec A = -2/√3 (neglecting this value as A is acute angle) Therefore, sec A = 2/√3 Using Trigonometric Identity: 1 +…

If sin A = 1/2 , find all the Trigonometric Ratios – Class 10
In this blog, let’s understand how to find all six trigonometric ratios when sin A = 1/2 using Triangle and Identity method 1st Method : Triangle Method We are given: sin A = 1/2 By definition, sin A = Perpendicular / Hypotenuse So, we can assume: Perpendicular (P) = 1 Hypotenuse (H) = 2 We assume the simplest…
