I hope it is ok to ask this general question. I am looking for examples of how to solve simultaneous differential equations using Mathematica. I would prefer examples that do not use manipulations as shown in the demonstration projects. Thanks

Hello, from your question it isn't clear whether you want to solve the equations analytically (DSolve) or numerically (NDSolve). If you look into the help pages for DSolve, then the first "neat example" shows a system of 2 equations. Of course also the second heading of DSolve shows the necessary calling syntax.

Look at the Help for DSolve. There is an example of the solution of three coupled first order equations. Kevin On 7/13/2011 3:11 AM, J and B wrote: > I hope it is ok to ask this general question.

I should have added that the example I referred to in the DSolve Help is under Neat Examples. Kevin On 7/13/2011 3:11 AM, J and B wrote: > I hope it is ok to ask this general question.
