Ex 2 1 11 Find Value Tan 1 1 Cos 1 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. 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.

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. 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. Find the value of `cos(x 2)`, if tan x = `5 12` and x lies in third quadrant. if –1 ≤ x ≤ 1, the prove that sin –1 x cos –1 x = `π 2` prove that: tan –1 x tan –1 y = `π tan^ 1((x y) (1 xy))`, provided x > 0, y > 0, xy > 1. the value of `tan(cos^ 1 4 5 tan^ 1 2 3)` is . find the value of `sin(2cos^ 1 sqrt(5) 3.
