Closed form solution of differential equation

  1. Mar 17, 2012 #1
    i have got a solution of my differential equation - consists of Bessel function and hyper-geometric function.............should i call it as a closed form solution?

    and i would also like to know about the importance of closed form analytical solution of any problem................what is the greatness of analytical solution over numerical solution?

    thank you..............

    Whether you consider it closed-form or not is really just semantics. Sometimes closed-form just means "not expressed as a power series" (in which case you would have a closed-form solution to your equation); other times it refers to "elementary functions" (in which case you would not).
