 Sep29 awarded Student Sep9 awarded Scholar Sep9 awarded Supporter Sep9 accepted Problem while solving system of two second order non linear coupled differential equations using NDSolve function Sep9 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. Sep9 comment Problem while solving system of two second order non linear coupled differential equations using NDSolve function 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. Sep9 comment Problem while solving system of two second order non linear coupled differential equations using NDSolve function How can I get the graphs of x vs t, and y vs t? Sep7 comment Problem while solving system of two second order non linear coupled differential equations using NDSolve function @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. Sep6 comment Problem while solving system of two second order non linear coupled differential equations using NDSolve function OK. I got it. Thanks for the trouble. Sep6 comment Problem while solving system of two second order non linear coupled differential equations using NDSolve function 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.
