Question

Which inverse trigonometric functions have the same domain?

Answer 1

B.) y=sin^-1 x and y=cos^-1 x

Explanation:

just took the test on edg and got 100%

Answer 2

B

Explanation:

1. The function
`y=\cos^(-1)x` has the domain:

`-1\le x\le 1.`

2. The function
`y=\sin^(-1)x` has the domain:

`-1\le x\le 1.`

3. The function
`y=\tan^(-1)x` has the domain:

`-\infty\le x\le \infty.`

Thus, option B is true, the functions
`y=\cos^(-1)x` and
`y=\sin^(-1)x` have the same domain.
