We are given the derivative of f: f′(x) = cos(x) + 10/x. Compute f(2) − f(1)
Can someone please help??

compute the integral of f′(x) = cos(x) + 10/x. after getting that f(x) do f(2) and f(1) then find f(2) − f(1)

thanks Mark. It takes me a while to figure things out, so give me a few moments and I'll write if I have further questions.

@mark_o. so, the integral of f'(x) = cos(x) + 10/x is sin(x) = 10 ln(x) Correct? So, for f(2) we would write this as sin(2) + 10 ln(2) and f(1) = sin(1) = 10 ln(1)?? How am I doing so far??

So, next which is a ridiculous question, how do I calculate f(2)  f(1)?
