Exact Differentials
HomotopyOperator is almost worth the price of admission for DifferentialForms.m by itself. Integral together with HomotopyOperator definitely are, IMHO.

Added a Simplify statement to HomotopyOperator line and rephrased last line to have antiderivatives differ by a constant, not an exact 0-form

Find Solution to Exact ODE with 4 Variables?
WOW!! You're 100% "The Man"!! FYI, here is the StackExchange post using your answer to answer @JinsongYang "tricked out" (IMHO) questions about "angular" work integrals on SO(3) math.stackexchange.com/questions/2137879/… Thanks again so much, this was awesome; it's great being a mathematician in 2020!

Find Solution to Exact ODE with 4 Variables?
Thank you so much, this is awesome! If I could trouble you or someone a little more, how do I do something like phi[w_, x_, y_, z_] := dsolvePotentialPDE[ D[phi1[w, x, y, z], {{w, x, y, z}}] == D[wxy*z, {{w, x, y, z}}], phi1[w, x, y, z], {w, x, y, z}][[2]] to assign to phi[w_,x_,y_,z_] the formula as the output to the solution to the DE, possibly but not necessarily without the constant of integration (I really need to RTFM as some point)?
