Use the "mixed partials" check to see if the following differential equation is exact. if it is exact find a function f(x, y) whose differential, df(x, y) gives the differential equation. that is, level curves f(x, y)=c are solutions to the differential equation: dydx=3x3+2y−2x−y2 first rewrite as m(x, y)dx+n(x, y)dy=0 where m(x, y)= equation editor equation editor , and n(x, y)= equation editor equation editor . if the equation is not exact, enter not exact, otherwise enter in f(x, y) as the solution of the differential equation here
