differential equations - simple cases:
  1. derivative as function of the independent variable: d n y d x n = f n ( x )
  2. separation of variables: dy dx = f y ( y ) f x ( x )
  3. missing independent variable: F 1 ( y, dy dx ,...., d n y d x n )=0
  4. missing dependent variable: F 1 ( x, dy dx ,...., d n y d x n )=0
