Characteristic (Partial Differential Equation)
Paths in a 2-D plane used to transform Partial Differential Equations intosystems of Ordinary Differential Equations. They were invented by Riemann.For an example of the use of characteristics, consider the equation
Now let
. Since
it follows that
, 
, and 
. Integrating gives 
, 
, and
, where the constants of integration are 0 and
