Question: In Exercises 1-2, verify the identity. 1. tan(sin -1x) = x / 1 - x2 2. cos(sin -1x) = 1 - x2 3. tan(sin -1

In Exercises 1-2, verify the identity.
1. tan(sin -1x) = x / √1 - x2
2. cos(sin -1x) = √1 - x2
3. tan(sin -1 x - 1 / 4) = x - 1 / √16 - (x - 1)2
4. tan(cos -1x + 1 / 2) = √4 - (x + 1)2 / x + 1
