I am still using Mathcad 11, and only sometimes Mathcad 15 (hate Framenet in XP).
I do not konw how to obtain discrete differentials. The following example may explain my problem:
In any case, how do I obtain, starting with the initial value y(x)=0, all the range values of y(x) shown in step (2) [i.e. 0,1,4,9] using DER2a or b?
Thank you for any suggestion,
Solved! Go to Solution.
Thank you very much for you effort. I downloaded the file and started to have a look. My expertise is limited, but I have learned so far that the range variables have some limitations. I shall come back after having studied your example.
You are welcome!
Its important in Mathcad to distinguish between range variables and vectors.
Find attached some excellent reading stuff by Stuart Bruff!!
Anthony, do you know the Euler method of ODE solution? I see it in your question.
See please one Mathcad websheet http://twtmas.mpei.ac.ru/mas/worksheets/Euler.mcd
@Werner Exinger @Valery Ochkov
what a wonderful feedbacks. Thank you very much! I wanted acknowledge your help even before downloading your - no doubt - instructive examples.
Form Werner first MC11 file I already learned the use of the "stack" command, which solves somewhat the addition of "0" in step 6. I'm still learning the rest. Definitely vector variables seem more flexible for manipulation than range variables. I shall come back with some more mathcad knowledge later, thanks to your files.
