Question

${sin}^{ - 1} \frac{1}{x} ?$
please answer it​

Answer 1

Answer:

HERE IS YOUR ANSWER

Step-by-step explanation:

We know that sin-1 x is defined for x ∈ [-1,1]

∴ f(x) = sin-1 √(x-1) is defined if

⇒ 0 ≤ √(x-1)≤ 1

⇒ 0 ≤ x - 1 ≤ 1 [∵√(x-1 ≥ 0 and -1 ≤ √(x-1 ≤ 1]

⇒ 1 ≤ x ≤ 2

∴ x ∈ [1,2]
