		Hermite Differential Equation
 
   | (1) |  
  This differential equation has an irregular singularity at  .  It can be solved using the series method
   | (2) |  
 
   | (3) |  
  Therefore,
   | (4) |  
  and
   | (5) |  
  for  , 2, ....  Since (4) is just a special case of (5),
   | (6) |  
  for  , 1, ....  The linearly independent solutions are then
 
  If  , 4, 8, ..., then   terminates with the Power  , and   (normalized so thatthe Coefficient of   is  ) is the regular solution to the equation, known as the Hermite Polynomial. If , 6, 10, ..., then   terminates with the Power  , and   (normalized sothat the Coefficient of   is  ) is the regular solution to the equation, known as the Hermite Polynomial.
 
 If  , then Hermite's differential equation becomes
    | (9) |  
  which is of the form   and so has solution
