Question

F (x) = 0,5 -sin x f(x)=-cos x

Answer 1

F (x) = 0,5 -sin x   f(x)=F'(x)=-cosx

f(x)=-cos x    F(x) =∫-cosxdx=-sinx+C 

Answer 2

It seems there might be a misunderstanding or a typographical error in your question. It appears you provided two functions, F(x) and f(x), and mentioned their expressions as:

1. F(x) = 0,5 - sin(x)
2. f(x) = -cos(x)

However, it's not clear what you want to know or do with these functions. If you could provide more context or specify your question, I'd be happy to assist you further. Do you want to find roots, calculate values, perform operations, or something else related to these functions? Please let me know how I can help!
