These are equations are true for any value of the variable that is there in the domain.

WebTo prove a trigonometric identity, we have to show that the identity is true for all values of the angle. For example, consider the following identity: \tan (\theta)+\cot (\theta)\equiv \sec (\theta)\cosec (\theta) tan(θ) + cot(θ) ≡ sec(θ)cosec(θ) We could substitute values of θ on both sides of the identity, and this would show that the ... WebSolution. Start by simplifying the left-hand side of the equation. sin2xtan2x = sin2x sin2x cos2x = cos2x. Now simplify the right-hand side of the equation. By manipulating the Trigonometric Identity, sin2x + cos2x = 1, we get cos2x = 1 − sin2x. cos2x = cos2x and the equation is verified.
