Difference method for solving the series has a lot of advantages. Lagrangian method of differential equations: from a 2011 National College Entrance exam Solution talking about from a 2011 National Science questions Solution talking about first text excerpt of one of 23 years ago. Then the reality of contact and thus introduce a complete system of differential equation theory. And further information on the results of the Russian mathematician forefront of the stability of the difference equations. Lagrangian method of differential equations: from a 2011 National College Entrance exam Solution talking about suitable for junior and senior high students. especially in mathematics Contestants. middle and high school mathematics teacher and Middle School Mathematics Olympiad coaches. but also as university teaching and student learning books and math enthusiasts interested in books.
