SUMMARY

A perfect derivative refers to a function that is the derivative of another function, specifically in the context of line integrals. In this discussion, it is established that the line integral of a perfect derivative around a closed loop is equal to zero, as demonstrated by the fundamental theorem of calculus. This is because when evaluating the limits of the integral, the starting and ending points are the same, resulting in a net value of zero. The concept is linked to the gradient of a function, denoted as grad(F).

PREREQUISITES
  • Understanding of line integrals in vector calculus
  • Familiarity with the fundamental theorem of calculus

I have never heard of the term perfect derivative before, but, from your problem, it sounds like you a referring to an example of a line integral in a field in which the function you are integrating happens to be the derivative of another function:\oint f dxwhere either:f = \frac {dF} {dx} or: f = \nabla \cdot \textbf{F}In either case, think about what the fundamental theorem of calculus would imply for a line integral of such a function on a closed loop. If this wasn't what you meant, my mistake, let me know.
