Integrate (frac{1}{x}) + cos x with respect to x

A.
(frac{1}{x^2}) + sin x + k 
B.
x + sin x – k 
C.
x – sin x + k 
D.
(frac{1}{x^2}) – sin x + k
Correct Answer: Option C
Explanation
(int frac{1}{x} + cos x = ln x – sin x + k)
Integrate (frac{1}{x}) + cos x with respect to x
(int frac{1}{x} + cos x = ln x – sin x + k)
