Trigonometry equations formulas for class 10th PDF
List of Trigonometry equations formulas for class 10th PDF – An equation involving one or more trigonometric ratios of unknown angles is called a trigonometric equation. A trigonometric equation can be written as Q1 (sin θ, cos θ, tan θ, cot θ, sec θ, cosec θ) = Q2 (sin θ, cos θ, tan θ, cot θ, sec θ, cosec θ), where Q1 and Q2 are rational functions.
Example: Let us consider an equation cos2x – 4 sin x = 1.
This is a trigonometric equation and not an identity as it is not satisfied for all values of x e.g. the equation is not satisfied at (2n + 1)π/4.
