The values of the trigonometric ratios of an angle do not vary with the lengths of the sides of the triangle, if the angle remains the same. 1) What does this statement mean? When we calculate sine, cosine, or tangent of an angle in a right-angled triangle, we use the sides of the triangle. For example, in a right…

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…
📚 Learn to Find All Trigonometric Ratios in 2 Minutes! Sin θ, Cos θ, Tan θ, Cosec θ, Sec θ, Cot θ | Class 10
Many students find this chapter confusing at first — but once you crack the Pandit Badri Prasad Trick, trust me, it becomes one of the easiest scoring topics. ✅ The 3 Sides of a Right-Angle Triangle Before jumping into ratios, know the 3 sides: 1️⃣ Perpendicular (Opposite Side) — side opposite to the given angle (except the…
