    Another easier way to test if a vector field is conservative is by finding the curl of the vector field, if the curl is a zero vector(i.e then the vector field is conservative, The curl will automatically check for all the cases that you have listed.

      How do you check if a 4-dimensional vector field is conservative, if curl only works for up to 3-dimensional fields?

    I absolutely love your work, but something that I believe is missing is the fact that using Clairaut's does not always correctly tell us whether a vector field is conservative or not as it does not account for singularities.

    Hi, doctor. What could happen in higher dimensions, like 4, 5, and so on. How could I know if a function is conservative when it is in a dimension higher than 3?

    • @DrTrefor
      @DrTrefor  4 года назад +7

      The same basic idea. You need to compare all the possible ways you take the partial of the ith component with respect to the jth variable to the partial with j and i reversed. If all of those match up, it is conservative.

    Dr. Bazett, first of all, thank you for the great video. I would like to ask you a question about this test you are presenting. I believe this "if and only if" property is called the Poincaré-Lemma, where it is stated that it applies only when the domain of F star shaped is (Star Domain), which in general any higher dimension R is. However, we might not be working with a star domain, for example F might be defined on R^2\{0}. In that case, can we still use this test or is it invalid? Thank you in advance!

    • @DrTrefor
      @DrTrefor  4 года назад +7

      Imagine the curve is a figure 8, and you are driving around and pointing your normal out the window to the left. Sometimes you are pointing INSIDE the curve, sometimes OUTSIDE. That's a problem for measuring the flux via the degre to which it is only going outside. SImply connected blocks that problem.
