comment Problem while solving system of two second order non linear coupled differential equations using NDSolve function
Thanks a lot! But why did Dt work, and x' didnt work. I also tried plotting x''. In this case, Dt[Dt] didnt work, but x'' worked. +1 and accepted answer. But it would be good if you could answer the question, I posed in this comment.

OK. I tried this command Plot[Evaluate[x'[t]/.s],{t,0,.7}], with x prime replaced by x, for the x vs t graph and it worked. But it is not giving me an answer for x prime itself. The graph is blank.

How can I get the graphs of x vs t, and y vs t?

@SjoerdC.deVries: Ok, I will keep that in mind. But I also wanted to know about other non Mathematica methods that I could use, the mathematica specific question was posted on this SE only.

OK. I got it. Thanks for the trouble.

Oh. How did you do this? Where do I enter the code actually? I myself entered it by create new -> package, and entered it in the input. Is this correct? Also, can I get a polynomial approximated function as the solution.
