Silly question about exact equations.

  1. Jun 28, 2013 #1
    Can you manipulate any exact equation to be a first order linear equation? if you are not concerned with which variable is the dependant one and which is the independant one. i.e. dx/dy or dy/dx?

    Certainly not. For example [itex]cos(x)dy- sin(x)dx= 0[/itex] is an exact equation but we cannot get rid of those trig functions.
