Find the domain of each of the following functions:
f(x) = sin–1x + sin–12x
Domain of 
lies in the interval [–1, 1].
–1 
1
Therefore, the domain of 
lies in the interval 
–1 
1
The domain of sin–1x + sin–12x is the intersection of the domains of sin–1x and sin–12x.
So, Domain of sin–1x + sin–12x is 
.
