SUMMARY
The discussion centers on the mathematical function defined by the integral $$f(x)=\int_{t=p}^{t=x} \frac{\cos t}{t} dt$$, specifically addressing the constant added to the integral. Participants clarify that if the integral starts at p=3, then the integral evaluates to 0 at x=3, necessitating the identification of the constant. The correct derivative is also confirmed as $$f'(x) = \frac{\cos x}{x}$$, with the condition that f(3) = 4, leading to the conclusion that the function can be expressed in the form of the integral with the appropriate constant added.
