ORDINARY DIFFERENTIAL EQUATIONS
Higher order differential equations with constant coefficients Method of variation of
parameters Cauchys and Legendres linear equations Simultaneous first order
linear equations with constant coefficients.
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

We are about to study a simple type of partial dif
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
