let f(x) = sqrt(1-sin(x))
What is the domain of f?
What is the domain of f'(x)?
The Attempt at a Solution
I understand that the domain of f is all real numbers not including every increment of 90 degrees, but im not sure how to state that.
I also found that f'(x) = (1/2 -sin(x))(-cos(x)) im not sure if thats correct though
