First off I'm sorry to post this, I've seen several different posts and topics about issues with plotting and I have read through the different pdfs and tutorials for SMath, but I still can't figure out how to use 2D plots. I've even gone as far as trying to copy several of the examples directly into SMath to see if it would make a difference, but I still can't get the plots to show up properly.





These are two of the examples I've tried copying but for some reason they aren't plotting correctly or even plotting at all. Is there a plugin I'm missing or is it just human error???

hi
did you type the array this way? r[i
btw here you can read about how to attach files and pictures on the forum.

No, o_o I thought the i's were added as subscripts using r.i but using [ instead of . looks like it fixed the problem.
It also looks like it solved the same issue with another example that was causing trouble.
Thank you for the help and for the link!!
