### Inverse Trigonometric Functions

Basics Concepts:  the domain and range of trigonometric functions.

sine function, i.e., sine : R → [– 1, 1]

cosine function, i.e., cos : R → [– 1, 1]

tangent function, i.e., tan : R – { x : x = (2n + 1)π/2, n ∈ Z} →R

cotangent function, i.e., cot : R – { x : x = nπ, n ∈ Z} →R

secant function, i.e., sec : R – { x : x = (2n + 1)π/2, n ∈ Z} →R – (– 1, 1)

cosecant function, i.e., cosec : R – { x : x = nπ, n ∈ Z} →R – (– 1, 1)

### Properties of Inverse Trigonometric Functions

Some properties of inverse trigonometric functions are listed below:

sin−1(1/x) = cosec−1x, x ≥ 1 or x ≤ −1

cos−1(1/x) = sec−1x, x ≥ 1 or x ≤ −1

tan−1(1/x) = cot–1x, x > 0

(i) sin–1(–x) = – sin–1 x, x ∈ [– 1, 1]

(ii) tan–1(–x) = – tan–1 x, x ∈ R

(iii) cosec–1(–x) = – cosec–1 x, | x | ≥ 1

(i) cos–1(–x) = π – cos–1 x, x ∈ [– 1, 1]

(ii) sec–1(–x) = π – sec–1 x, | x | ≥ 1

(iii) cot–1(–x) = π – cot–1 x, x ∈ R

(i) sin–1 x + cos–1 x = π/2, x ∈ [– 1, 1]

(ii) tan–1 x + cot–1 x = π/2, x ∈ R

(iii) cosec–1 x + sec–1 x = π/2, |x| ≥ 1
