Ex 2 2 11 Find Tan 1 2 Cos 2 Sin о Transcript. ex 2.2, 8 find the value of tan 1 ["2 cos " (2"sin−1" 1 2)] solving sin 1 (𝟏 𝟐) let y = sin 1 (1 2) sin y = 1 2 sin y = sin (𝝅 𝟔) range of principal value of sin −1 is [(−𝜋) 2, ( 𝜋) 2] hence, y = 𝝅 𝟔 rough we know that sin 30° = 1 2 θ = 30° = 30 × 𝜋 180 = 𝜋 6 since 1 2 is positive principal value is θ i.e. 𝝅 𝟔 now solving tan 1 ["2 cos. Transcript. ex 2.1, 11 (method 1) find the value of tan−1 (1) cos−1 (−1 2) sin 1 (−1 2) solving tan−1 (1) let y = tan−1 (1) tan y = 1 tan y = tan (𝝅 𝟒) ∴ y = 𝝅 𝟒 since range of tan−1 is (−π 2,π 2) hence, the principal value is 𝝅 𝟒 solving cos−1 ( (−𝟏) 𝟐) let y = cos−1 ( (−1) 2) y = 𝜋.
Ex 2 2 11 Find Tan 1 2 Cos 2 Sin о Use inverse trigonometric functions to find the solutions, and check for extraneous solutions. a basic trigonometric equation has the form sin (x)=a, cos (x)=a, tan (x)=a, cot (x)=a. the formula to convert radians to degrees: degrees = radians * 180 π.

The 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. Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. in particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths. the field emerged in the hellenistic world during the 3rd century bc from applications of geometry to astronomical.
