I do not know the answer to your second question, > maybe someone else can answer this. > > Sirpa Saarinen > saarinen at wolfram.com You can certainly linearize any non-linear DE by treating a variable as a constant, solving the remainder and iterating on the "constant" one. The broader response to your question, though, is that mathematica can certainly solve a non-linear differential equation just like c or fortran can. It is a powerful programming language, not just a collection of nifty functions.
