Step-by-step explanation:
Given:
As the domain for the inverse sine function is 1 ≤ x ≤ 1 as this is the range for the sine function.
The range for the function is the same as the range for the cosine function, 1 ≤ y ≤ 1
As
So, using the identity
As the sin and inverse sin function do cancel each other, so only x² is left.
Hence,
