Exact and Nonexact Equations
All the techniques we have reviewed so far were not of a general nature since in each
case the equations themselves were of a special form. So, we may ask, what to do for
the general equation
Let us first rewrite the equation

Change is intrinsic in the universe and in the world around us; the world is in motion.
Attempts to understand and predict change often involve creating models reflecting rates
of change. Translating information abo
