WebThe Pythagorean Identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan(− θ) = − tanθ. cot(− θ) = − cotθ. Websinθ= 1+x 21 or sinθ=− 1+x 21. ∴sin(cot −1x)=(1+x 2) − 21 or sin(cot −1x)=−(1+x 2) − 21. Opt:[D] is the correct answer. Solve any question of Inverse Trigonometric Functions …
